Make sure that calls to super class methods from mixin application
stubs are always generated using `super` and not `this`.
Replacing `super` by `this` should not be used as non-virtual field access optimization in forwarding stubs that intend to redirect to the super class members (using `this` redirects to itself and causes infinite recursion).

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.

>
> The main goal was to reduce the number of expensive type checks

> 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,

>
> The change has a memory cost: The `_FutureListener<S,T>` class,

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!");
}
```
from hanging the runtime by busily searching for the end of a cycle.

Fixes a memory leak issue where statics that are set but never
read before a hot restart are never reset and the functions to
set them are never garbage collected.
Update and add more tests for this specific scenario that inspect
the number of fields that will be reset during a hot restart.

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.

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.

Expandos collide after a hot restart. This currently fails because
the DDC implementation uses a static field (_keyCounter) to compute a
unique name for each expando. After a hot-restart the counter gets reset
and keys get reused accidentally.
A hacky fix would be to ensure this field is not reset after restarts,
but a more robust fix would be to use a weak map implementation like
dart2js does.
