This CL implements `WeakReference` in the VM.
* This reduces the size of weak references from 2 objects using 8 words
to 1 object using 4 words.
* This makes loads of weak reference targets a single load instead of
two.
* This avoids the fix-point in the GC and message object copying for
weak references. (N.b. Weak references need to be processed _after_
the fix-point for weak properties.)
The semantics of weak references in messages is that their target gets
set to `null` if the target is not included in the message by a strong
reference.
The tests take particular care to exercise the case where a weak
reference's target is only kept alive because a weak property key is
alive and it refers to the target in its value. This exercises the fact
that weak references need to be processed last.
Does not add support for weak references in the app snapshot. It would
be dead code until we start using weak references in for example the
CFE.
This CL does not try to unify weak references and weak properties in
the GC or messaging (as proposed in go/dart-vm-weakreference), because
their semantics differ enough.

For `asyncExpectThrows`, instead of taking a function,
then checking if that function can be called with zero arguments,
and then immediately calling it and checking that it returns a future,
just take the future as argument.
Since synchronus errors from calling the function were not caught
anyway, doing the entire `Future` computation directly shouldn't
change behavior.
Also make `asyncExpectThrows` and `Expect.throws` return the caught error,
so that you can use normal `Expect.something` checks on it afterwards,
instead of doing that in the `check` function.
That basically makes the `check` function unnecessary (but hard to remove
with the existing test corpus using it heavily).
This makes some uses of the `asyncExpectThrows` function slightly more
complicated, those that have no other way to create a future than calling
the argument function anyway, but other uses become simpler
when they can avoid adding the function wrapper.
TEST= Refactoring. If the tests keep running, it's successful.

This change makes a static function more permissive, and is not expected

(It does mean that you need Dart 2.15.0 to use the function with

That means anyone using a 2.15 SDK should assume that they need a 2.15
SDK to use it, and someone using a 2.14 SDK will not see the argument
as nullable. If anyone uses `@Since` annotations for anything at all.)

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`.

Previously, when encountering identifiers in metadata on a class's
type parameter, the analyzer would resolve them using the type
parameter scope, but then fall back on using implicit `this`. The CFE
would resolve them using the class body scope. In both cases, the end
result was that the annotation could refer to static class members.
This change brings the behavior of both the analyzer and the CFE in
line with the spec, by preventing the use of implicit `this` in these
annotations, and resolving them in the type parameter scope.
This is not expected to break any code in practice, because
annotations on type parameters are rare, as are annotations referring
to static class members, and the overlap between these two should be
negligibly small.

Removes the lazy loading of the underlying type in LazyJSTypes.
As such, this removes the need to keep AnonymousJSType and
LazyJSType separate, and is therefore refactored to
PackageJSType. Similarly, subtyping is fixed such that
PackageJSTypes are all subtypes of each other.

This CL
* Removes conditional Skip markers in status files
* Removes some outdated TODOs in the code
* Deletes tests/lib_2/isolate/isolate_stress_test
=> It's skipped everywhere, we no longer support isolates on web
* Fixes standalone{,_2}/io/directory_list_sync_test:
=> Instead of relying on the Platform.script which could be an ELF
file lying somewhere else, use Platform.executable instead
* Fixes standalone{,_2}/io/unix_socket_test:
=> The server used `sub.cancel()` to close it's reading end while
the client tried to write to it. This is racy.
If the server goes first, the write on client will throw (since
no error listener was installed on socket.done)
Avoid the race by coordinating client/server.

We use message passing as comunication mechanism between isolates.
The transitive closure of an object to be sent is currently serialized
into a snapshot form and deserialized on the receiver side. Furthermore
the receiver side will re-hash any linked hashmaps in that graph.
If isolate gropus are enabled we have all isolates in a group work on
the same heap. That removes the need to use an intermediate
serialization format. It also removes the need for an O(n) step on the
receiver side.
This CL implements a fast transitive object copy implementation and
makes use of it a message that is to be passed to another isolate stays
within the same isolate group.
In the common case the object graph will fit into new space. So the
copy algorithm will try to take advantage of it by having a fast path
and a fallback path. Both of them effectively copy the graph in BFS
order.
The algorithm works effectively like a scavenge operation, but instead
of first copying the from-object to the to-space and then re-writing the
object in to-space to forward the pointers (which requires us writing to
the to-space memory twice), we only reserve space for to-objects and
then initialize the to-objects to it's final contents, including
forwarded pointers (i.e. write the to-space object only once).
Compared with a scavenge operation (which stores forwarding pointers in
the objects themselves), we use a [WeakTable] to store them. This is the
only remaining expensive part of the algorithm and could be further
optimized. To avoid relying on iterating the to-space, we'll remember
[from, to] addresses.
=> All of this works inside a [NoSafepointOperationScope] and avoids
usages of handles as well as write barriers.
While doing the transitive object copy, we'll share any object we can
safely share (canonical objects, strings, sendports, ...) instead of
copying it.
If the fast path fails (due to allocation failure or hitting) we'll
handlify any raw pointers and continue almost the same algorithm in a
safe way, where GC is possible at every object allocation site and
normal barriers are used for any stores of object pointers.
The copy algorithm uses templates to share the copy logic between the
fast and slow case (same copy routines can work on raw pointers as well
as handles).
There's a few special things to take into consideration:
* If we copy a view on external typed data we need to know the
external typed data address to compute the inner pointer of the
view, so we'll eagerly initialize external typed data.
* All external typed data needs to get a finalizer attached
(irrespective if the object copy suceeds or not) to ensure the
`malloc()`ed data is freed again.
* Transferables will only be transferred on successful transitive
copies. Also they need to attach finalizers to objects (which
requires all objects be in handles).
* We copy linked hashmaps as they are - instead of compressing the
data by removing deleted entries. We may need to re-hash those
hashmaps on the receiver side (similar to the snapshot-based copy
approach) since new object graph will have no identity hash codes
assigned to them. Though if the hashmaps only has sharable objects
as keys (very common, e.g. json) there is no need for re-hashing.

Adds static errors in web backends requiring external members to be
annotated with @JS(). Members can be annotated directly, or on the
enclosing class or library.
Also removes duplicate checks in dart2js for non-native external
members that are now covered by the checks on external @JS members.

doesn't have a JS annotation. This relaxes DDC to do the same.
