Compilers named "dartdevc" and "dartdevk" should be listed together
at all locations. These are now aliases for the same compiler
across different configurations.
In the future these names should converge on "dartdevc".
Some skipped tests for "dartdevc" no longer need to be skipped but
currently there are no configurations are running those tests with
that compiler name so removing the skips shows no change in test
results.

On ia32 the CFE will run from a kernel file instead of an AppJit
snapshot. This is generally not that fast. In debug mode the JIT will
have various additional verifications turned on in the runtime (e.g.
flow graph checker runs, ...) - which will make it very slow.
So we should give all tests on debug-ia32 extra time.

The current implementation uses a specialized version of the
pending-event queue used by stream subscriptions to remember
pending events.
That makes the queue polymorphic, and slightly more complicated than
necessary, and that again makes further refactorings of the
Stream implementation harder.
This change moves the logic from the specialized pending-queue
into a simple function instead, so you only pay for it if you
actually use `Stream.fromIterable`.
Also allows `Stream.fromIterable` to be listened to more than once.
(It uses `Stream.multi` for the general async+sync controller API,
and it would cost extra code to make it only work once.)

This is a major rewrite of the `_Future` class,
which is the default implementation of the `Future` interface.
The main goal was to reduce the number of expensive type checks
in the internal passing around of data.
Expensive type checks are things like
* `is _Future<T>` (more expensive than just `is _Future`, the latter
can be a single class-ID check.
* Covariant generic parameter checks (using `T` covariantly in a
parameter forces a run-time type check).
Also removed some plain unnecessary casts and turned some
implicit casts from `dynamic` into `unsafeCast`s.
This seems to be an success, at least on very primitive benchmarks, according to Golem:
FutureCatchErrorTest 41.22% (1.9 noise)
FutureValueTest 46.51% (2.8 noise)
EmptyFutureTest 59.15% (3.1 noise)
FutureWhenCompleteTest 51.10% (3.2 noise)
A secondary goal was to clean up a very old and messy class,
and make it clearer for other `dart:async` how to interact
with the future.
The change has a memory cost: The `_FutureListener<S,T>` class,
which represents a `then`, `catchError` or `whenComplete`
call on a `_Future`, now contains a reference to its source future,
the one which provides the inputs to the callbacks,
as well as the result future returned by the call.
That's one extra memory slot per listener.
In return, the `_FutureListener` now does not need to
get its source future as an argument, which needs a covariant
generic type check, and the methods of `_Future` can be written
in a way which ignores the type parameters of both `_Future`
and `_FutureListener`, which reduces complex type checks
significantly.
In general, typed code is in `_FutureListener`, which knows both
the source and target types of the listener callbacks, and which
contains the futures already at that type, so no extra type checking
is needed.
The `_Future` class is mostly untyped, except for its "public"
API, called by other classes, which checks inputs,
and code interacting with non-native futures.
Invariants ensure that only correctly typed values
are stored in the untyped shared `_resultOrListeners` field
on `_Future`, as determined by its `_state` integer.
(This was already partially true, and has simply been made
more consistent.)
Further, we now throw an error in a situation that was previously
unhandled: When a `_Future` is completed with *itself*.
That would ensure that the future would never complete
(it waits for itself to complete before it can complete),
and may potentially have caused weird loops in the representation.
In practice, it probably never happens. Now it makes the error
fail with an error.
Currently a private `_FutureCyclicDependencyError` which presents
as an `UnsupportedError`.
That avoids code like
```dart
import "dart:async";
void main() {
var c = Completer();
c.complete(c.future); // bad.
print("well!");
var d = Completer();
d.complete(c.future);
print("shucks!");
}
```

Static class members could technically be mapped to a name with dots,
but in the early days of JSInterop we thought this was not necessary
since it could also be modeled as a top-level member or by adding
additional classes and exposing the member as a simple name on a deeper
class.
This invariant was assumed by DDC (which crashed if this was not the
case) and ignored by dart2js.
This change adds a static check to ensure both compilers act
consistenlty.

some minor additions for the exponentiation (`**`) operator, supporting
these through `dart:js_util` is trivial.

Right now the implementation of `Isolate.spawnUri(<uri>, ...)` in
the standalone embedder is to ignore `<uri>` and make the spawnned
isolate from the same AOT snapshot as the main isolate.
This is very confusing and very incorrect.
Instead `Isolate.spawnUri()` should work if-and-only-if the given
`<uri>` points to a valid and compatible AOT snapshot. If not, it should
throw an appropriate exception.

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.
