Adds a @pragma("vm:recognized", <kind>) to all recognized methods, where
<kind> is one of "intrinsic", "graph" or "other", corresponding to the
kind of recognized method.
When running in debug mode, it is checked that all recognized methods
are marked with the correct kind of pragma, and that all methods marked
with the pragma are in fact recognized.
This enables kernel-level analyses and optimizations to query whether
a method is recognized by the VM.
TEST=Asserts that check the correspondence both ways, covered by test

Simple calls to `List.generate` are expanded into a list allocation
and a loop. This generates better code for several reasons:
- There is no overhead for the function argument (closure allocation,
closure type, closure class)
- Global type inference is more precise since each List.generate list
is tracked separately, and the assignments in the loop give better
inference to the collection's element type.
To get precise element type inference, there are two new JSArray
constructors. Global type inference starts with the element type being
bottom for these elements, avoiding spurious nulls in the inferred
type.

Since ddc would require a potentially breaking change to emit these
checks in unsound mode without opt-in and it's currently not possible
to emit these checks only in opt-in with dart2js, both are changed
to only emit checks in sound mode. In ddc, calling convention is
changed conditionally on sound mode as well to avoid emitting
unnecessary code in unsound mode.

The covariance optimization assumed that private members only occur
in the library in which they are private. This is not the case. The

- use parameter types passed to IncrementalCompiler.compileExpression
for compilation of the synthetic function containing the expression
- updated expression compiler tests
Note: some expressions that previously compiled wouldn't now
Example:
** package:test/library.dart **
class TestLibraryClass {
final int field;
final int _field;
TestLibraryClass(this.field, this._field);
}
** main.dart **
import 'package:test/library.dart';
void main() {
var instance = TestLibraryClass(1, 2);
print('$instance'); // Breakpoint here
}
Expression:
`instance._field`
Previously, the incremental compiler would compile the expression
to kernel due to the type of instance being Dynamic. That compilation
result made it impossible for dartdevc to generate correct code due
to missing type information.
Now, the compilation will fail with "Getter isn't defined"
error. To properly evaluate private fields now, we would need
the CFE to support a special mode for expression compilation
where private fields from other libraries are allowed.

- Updated tests to work with DDC (for simulating webdev)
- Disabled tests that work with bazel kernel worker for now
as it does not generate full dill files yet
- Addressed code review comments from the prototype version:
https://dart-review.googlesource.com/c/sdk/+/157005
Details:
Currently, in flutter tools, expression evaluation is supported via
expression compilation, which is done by the incremental compiler in
the frontend server. The same incremental compiler is used for initial
application compilation, incremental code compilation for hot reload,
and any number of expression compilation requests.
In google3, the apps are typically too large to be compiled as a whole
in memory by the frontend server. Build in google3 is currently done by
blaze, as a distributed build using a task dependency graph. Build tasks
output kernel outline files as an interface between components produced
by individual tasks.
We are proposing an implementation of the expression compilation in
google3 that is taking advantage of full kernel files produced by the
build (supporting build changes to follow). This change introduces a
small server based on dev_compiler, which can handle following requests:
- update: load full kernel for given modules (done on app start)
- compileExpression: compile expression in a given library and module
(done when paused on a breakpoint)
Expression compilation uses previously loaded kernel files for the
application component and its dependencies to compile an expression.

All of the backends (dart2js, DDC, VM) were checking if the invocation
name was tagged with "set:" and appending "=" to the name if so.
Instead, we can simply have the CFE perform this logic at the callsite.
Note that the name of the setter itself is still unchanged. Backends may
still need to generate the correct name themselves when handling NSMs
via code paths other than instantiateInvocation.

- using the --no-nnbd flag results in the SDK being built in a
directory which has the 'Legacy' suffix added to it
(e.g: out/DebugX64Legacy)
- the '--enable-experiment=non-nullable' flag still needs to be passed
in during execution so that CFE runs in that mode. This is different
from the 'null_safety' flag

For the cases of implicit bounds like `<T>` the default value
should be `dynamic` when instantiating and no type parameter is
provided. This change fixes this cases.
For explicit bounds like `<T extends Object?>` or
`<T extends Object*>` the default values should be `Object?` or
`Object*`. This change breaks these cases by defaulting to
`dynamic`.
Filed: https://github.com/dart-lang/sdk/issues/41539
I believe this is the correct trade off right now because the
implicit bounds like `<T>` are more likely to appear compared to
`<T extends Object?>` or `<T extends Object*>`.

- Add a work around to avoid ever creating legacy or nullable versions

This is a breaking change. https://github.com/dart-lang/sdk/issues/40709
This change makes the HeaderValue parsing more strict in two invalid
edge cases, supports parameters with null values as a feature, and fixes
toString() so it always produces tokens or quoted-strings valid per RFC
7230 3.2.6.
The empty parameter value without double quotes (which is not allowed by
the standards) is now parsed as the empty string rather than null. E.g.
HeaderValue.parse("v;a=").parameters now gives {"a": ""} rather than
{"a": null}.
Invalid inputs with unbalanced double quotes are now rejected. E.g.
HeaderValue.parse('v;a="b').parameters will now throw a HttpException
instead of giving {"a": "b"}.
The HeaderValue.toString() method now supports parameters with null
values by omitting the value. E.g.:
HeaderValue("v", {"a": null, "b": "c"}).toString()
now gives
v; a; b=c
This behavior can be used to implement some features in the Accept and
Sec-WebSocket-Extensions headers.
Likewise the empty value and values using characters outside of RFC 7230
3.2.6 tokens are now correctly implemented by double quoting such values
with escape sequences. E.g.:
HeaderValue("v",
{"a": "A", "b": "(B)", "c": "", "d": "ø", "e": "\\\""}).toString()
now gives
v;a=A;b="(B)";c="";d="ø";e="\\\""
The NNBD migration required making subtle changes to some dart:io
semantics in order to provide a better API. This change backports one of
these semantic changes to the unmigrated SDK so any issues can be
discovered now instead of blocking the future SDK unfork.

Because we cache on instances of type objects, all "type"-ish constructs in DDC must be pre-initialized if we want to avoid any hasOwnProperty checks (which are slow).
1) We now consult legacy/nullable caches earlier when wrapping types, as the downstream logic can be much slower than a lookup.
2) We cache on nullble and legacy wrappers themselves as well as just the underlying object (formerly we cached on just the latter) for faster lookups.
3) We attach local caches upfront, maintaining monomorphicity during hot code paths.
This improves regressions for opt-out worst-case tests from (120 us -> 2100 us) to (120 us -> 500 us) and weak mode tests from (120 us -> 1100 us) to (120 us -> 330 us).

* FutureOr<Null>? is normalized to Future<Null>* instead of

* There is no runtime normalization of FutureOr<T?>?. This
should have no effect since nullable types can not yet

HttpHeaders use lowercase by default for all headers, since it is supposed to be case insensitive. Some servers incorrectly treat case as significant, however, and expect headers with capitalization or in uppercase. The current implementation forces headers to be lower cases when adding values. Users cannot even manually modify the headers.
This change removes this restriction here so that users can modify the headers to whatever form they want. The new behavior is backwards compatible except if class was implemented. All headers inside http.dart are written as lower cases, adding values to HttpHeaders is still receiving lower cases input.
The other cl (https://dart-review.googlesource.com/c/http_multi_server/+/121411) migrates multi_headers.dart to be compatible with this change.
