We use an extension getter instead of an instance getter because
it doesn't conflict with any potential existing or future enums
which want an element named `name`.
Keeping the namespace for enum elements open is a priority.
We currently only reserve `index` and `values`.
BUG: https://github.com/dart-lang/language/issues/1511
Fixes language issue #1511, which is a long-standing request,
and should replace a number of alternative implementations
which are based on parsing the `toString()`.
This version has two fields on the shared superclass, the index
and private name, and has a separate `toString` for each `enum` class
which hard-codes that enum's class name.
An earlier version had both `"name"` and `"ClassName.name"` as fields
to be able to reuse the same `toString` method on all enum classes,
but that cost too much for JS compiled code.
Even having just `ClassName.` as a field and then combining inside
`toString` requires more code to create the enum instances.
Instead this version hardcodes the `ClassName.` string once
in the `toString` method, which means each enum class has its own
toString (which can *potentially* be tree-shaken then.)
This still tree-shakes slightly worse than the previous implementation
where every enum class had its own `index` and `_name` fields
independent of each other, which could then be tree-shaken independently.
However, the `index` was already made an interface member with the
addition of the `Enum` interface, so code which accesses `.index`
on something of the `Enum` supertype could prevent tree-shaking of
all enum classes' `index` fields.
Likewise any general access to the "name" of an enum would necessarily
do the same for the name.
This CL makes up for some of that by sharing more implementation
between enum classes.

When testing the subtype relation between two generic function types,
uninstantiated type variables can appear as an argument or return type
of one function while a concrete type appears in corresponding
position of the other function. A subtype relation can be established
if the bound of the type variable is a subtype of the concrete type.
For example given a type variable T with bound B and a concrete type
C we can say:
T <: C when T <: B <: C holds.
T <: B is true by the definition of interface subtypes `T extends B`.
This change adds a test for B <: C.
Add a new class used only when it appears we may need to test these
subtype relations. The class is used to plumb the bound information
of type variables further into the subtype check algorithm where it
is now tested.
Add a top level variable to index the total number of type arguments
seen during a subtype check through nested function types.

The WebSocket abstract class was changed to allow an optional parameter called customClient that takes in a HTTPClient and passes it to the WebSocket Implementation.
The WebSocket implementation takes the customClient, checks if its null, if its not null, it uses the customClient in place of the static HTTPClient that the WebSocket Implementation offers.
This custom client does not override the static HTTPClient, so all previous functionality remains the same when the customClient is not present.

- all core libraries and tests are migrated to use the annotation;
Once this CL lands and rolls we will edit internal and external embedders

This CL introduces immutable maps and sets in the VM backend but does
not yet target them from the frontend. The changes are tested by unit
tests constructing these immutable maps and sets.
This CL introduces immutable variants of the hash map and set in
compact_hash.dart and recognizes them in the VM. The immutable ones
use a different mixin with a different recognized method for accessing
members.
* Data list is an immutable list with a different cid. (Otherwise the
optimizer notices that immutable and mutable lists cannot be equal.)
* Index is a nullable mutable typed data. (Otherwise optimizer removes
necessary null checks.)
* Index should use a store-release barrier when written to.
Multiple isolates might lazily compute the index for const sets and
maps. This is fine because all identityHashCodes and hashCodes are
guaranteed to be race-free. The later isolates will override the index
pointer with an identical index.
This CL does not introduce support for using these immutable maps and
sets in AOT (clustered_snapshot) and in messages to other isolates
(message_snapshot) because that is harder to test with unit tests. That
will be added in the follow-up CL.

It's a badly designed class, but this change makes it slightly better.
(We should consider moving it to package:collection and removing it from
the platform libraries. Eventually.)
The changes decouples the public `DoubleLinkedQueueEntry` class from
the actual queue implementation classes, avoiding the latter having
to share a generic `_Link<DoubleLinkedQueueEntry>` interface
which would force them to do otherwise unnecessary casts.
The public class should have been abstract, but isn't.
It's mainly used as the API of the entries exposed by DoubleLinkedQueue,
but it can also be used by itself to build double-linked lists that are
not part of a Queue, and the class can be extended.
If anyone does either, it should keep working, so it needs to be a concrete,
self-contained class with a generative constructor.
That class is moved to dart:_internal to avoid its private
implementation fields from interfering with the queue implementation classes,
which have similar fields, but can now have them at different types.
That's a hack, but it works.
The internal implementation of the DoubleLinkedQueue and its entries
are updated to better follow current programming idioms, and avoids
having fields on classes which don't need them.
Also fixes#27920
(`clear`ing a list now detaches each entry from the list so later `.contains`
won't give the wrong answer).
And moves queue tests from tests/corelib to tests/lib/collection,
since Queue isn't exposed by `dart:core`.

`int` variables can attain NaN values because web int arithmetic
implemented by JavaScript numbers (doubles) is not closed under many
operations. It is possible get NaN using only addition:
int a = 1, b = -1;
while (a + a != a) { a += a; b += b; }
int nan = a + b;
On the VM, a, b and nan are all zero.
On the web, a, b and nan are Infinity, -Infinity and NaN, respectively.
Since NaN can leak into int arithmetic, is it helpful if bounds checks
catch NaN indexes. NaN compares false in any comparison, so a test
of the form
if (index < 0 || index >= a.length) throw ioore(a, index);
fails to detect a NaN value of `index`.
This is fixed by negating the comparisons, and applying De Morgan's law:
if (!(index >= 0 && index < a.length)) throw ioore(a, index);
These changes have been applied to JSArray.[], JSArray.[]= and String.[]
For dart2js the change is a little more involved. Primitive indexing is
lowered to code with a HBoundsCheck check instruction. The code generated
for the instruction now uses, e.g. `!(i>=0)` instead of `i<0`.
This leads to a small code size regression.
There is no regression at -O4 since bounds checks are omitted at -O4.
At -O3 (where the regression is largest) the regression is
0.01% for cm
0.06% for flutter gallery -- array-heavy diff and layout
0.21% for Meteor -- array-heavy code
0.30% for Box2DOctane -- array-heavy code
I believe the regression can be largely alleviated by determining if
NaN is impossible at the index check, and if so, reverting to the smaller
code pattern. The analysis could be global, incorporating NaN into the
global abstract value domain, or a much simpler a local dataflow
analysis. Many indexes are loop driven and cannot reach infinity because
they are incremented by a small bump and eventually (even without a loop
guard) the index would stop growing when the increment falls below the
rounding error in O(2^53) iterations.

Also makes the `pub` shell script (and its .bat counterpart)
forward to a `dart __deprecated_pub` command that implements the
old top-level.
This allows us to get rid of pub.dart.snapshot saving ~15 MB in a
unzipped sdk.
The reason for not forwarding directly to `dart pub` is that the
interface is slightly different (for example there is no `dart pub --version`).
The only new commit in pub is: `3c2ce330 Expose toplevel as a command`

The transitive copy algorithm was missing support for [WeakProperty]s,
thereby ensuring that we only copy the values if the keys are reachable.
Furthermore we might need to re-hash [Expando]s - since the copied
objects start with no identity hash codes.
The CL also makes us avoid calling to Dart for each [Expando]
separately and instead use a list - just as we do in the re-hashing of
maps/sets.
We also move the C++ code to invoke rehashing logic into
DartLibraryCalls::*.

This PR provides additional info on the `substring` method, as it will throw a `RangeError` in the following cases:
* `start` is negative;
* `end` is negative;
* `start` is greater than `length`;
* `end` is greater than `length`;
* `start` is greater than `end`.
Although some of them are a little obvious, it's better to be explicit about the expectations. One could expect that, for example, that `'abc'.substring(0, 4)` would return `'abc'` instead of throwing.

Previously all functions objects returned by `dart.gbind()` would
contain the same 3 properties: name, length, and runtimeType. For
two distinct functions, if these three properties were the same
our constant canonicalization would incorrectly canonicalize to the
same value. Attaching the original function and the type arguments
used in instantiation ensures the const canonicalization will treat
different functions or instantiations as different values.
These values will also be used for equality checks proposed here:

This Cl ensures we use the same logic as for other miss handlers to

The changes to first land is: Avoid assuming the target can be called

The [DateTime.parse](https://api.dart.dev/stable/2.10.4/dart-core/DateTime/parse.html) method accepts out-of-range components. For example, parsing the string "2020-01-42" produces "2020-02-11".
This was raised as a bug in https://github.com/dart-lang/sdk/issues/11189, but after more than 7 years that issue was closed with the solution being "use parseStrict from the intl package" instead.
This pull request simply **updates the documentation of DateTime's _parse_ method** so that users know:
1. This is how the method behaves. Otherwise they might be surprised when it unexpectedly happens in their code.
2. This behaviour is a feature and not a bug. Otherwise they might raise another issue for it.
3. The _parseStrict_ method in the intl package exists. Otherwise they might reinvent the wheel.

Previously, when checking S <: T, we only checked if S and T had the
same interface name once. However, it's possible that redirections
eventually cause them to become equal. For example, if S is an interop
type and T is JavaScriptObject, after following the redirection from S
to JavaScriptObject, we end up checking JavaScriptObject <:
JavaScriptObject. Therefore, we need to recheck after following each
redirection.

Rename the test from `file.dart` to `io.dart` so that we can test all

The `unawaited` function in `dart:async` is intended for use with the `unawaited_futures` lint which is hopefully going to be part of the Dart recommended set of lints.
The `ignore` extension method is there to provide an alternative if you even want to ignore errors from a future. By having both, it makes the distinction clearer and makes it easier to not think one can be used for everything.

When rehashing linked hash maps we'll allow rehashing of hashmaps that
have deleted entries in them. This avoids making assumptions about the
state of a linked hashmap object at the time when it's transitively
copied.
It was split out of a follow-up CL that adds transitive object copies,
which will copy linked hashmaps as they are.

Calling `postEvent()` or `registerExtension()` from the
dart:developer library now sends messages via global functions
that can be set by the development infrastructure. For example,
these hooks are set by package:dwds.
When there is no debugger attached to the app, calling `postEvent()`
or `registerExtension()` will produce a warning once each to avoid
spamming the debug log with messages that do nothing.
For backwards compatibility, when a debugger is attached but the
hooks have not defined continue to write the events to the
console.debug log. This support will be removed when package:dwds
no longer reads from the log.

This adds the providesSymbol method to DynamicLibrary. It returns
whether the library contains a function with the given name.
As per dlsym(3), it is valid for dlsym to return nullptr in a success
case if the symbol actually has a NULL value. So I've changed the logic
to check for dlerror() after we invoke dlsym(), both in the existing
lookup and in the new method.

This CL adds FFI leaf calls by adding `lookupFunction(.., isLeaf)`
and `_asFunctionInternal(.., isLeaf)`, which generate FFI leaf calls.
These calls skip a lot of the usual frame building and generated <->

Such that runtime/include/internal/dart_api_dl_impl.h ends up in
include/internal/dart_api_dl_impl.h in the sdk release.
Long explanation:
https://dart-review.googlesource.com/c/sdk/+/164320 tried to recover the
folder structure but failed to do so correctly. It put
runtime/include/internal/dart_api_dl_impl.h in
include/runtime/dart_api_dl_impl.h rather than
include/internal/dart_api_dl_impl.h.
The gn copy action only supports a single `outputs` string.
https://gn.googlesource.com/gn/+/HEAD/docs/reference.md#var_outputs
This string can have 'placeholders'.
https://gn.googlesource.com/gn/+/HEAD/docs/reference.md#placeholders
The only placeholder that preserves the original folder structure,
without also nesting deeply inside folders is `source_target_relative`.
If `source_target_relative` inside sdk/BUILD.gn it starts including
`runtime/include/` in its path. So the only way to achieve the correct
copy is by doing it in runtime/include/BUILD.gn.
TEST=Manual testing, we don't have tests verifying the SDK structure.
