Riley Porter bfaf674479 Optimize js_util getProperty calls to lowered call to native JS.
No change in the generated JavaScript for dart2js based on both a small
foo.dart sample file and tests/lib/js/js_util/properties_test.dart

All changes in generated JavaScript for DDC are smaller and clearer:
  - foo.dart: https://paste.googleplex.com/4738045023617024

It also adds a hint for the error, providing alternatives for

Lasse R.H. Nielsen 478602ad79 Fix errors in Future implementation around Future<Future<X>>.
Previously, when completing a future with another future,
we always chained to the other future. This effectively awaits
the latter future and then completes the former with its result.
This is incorrect behavior if the former future is, say,
a `Future<Future<int>>` and the latter is a `Future<int>`.
In that case we *must not* await the latter future
because we can't complete the former future with an `int`.
We should just complete the future directly with the latter future
as a value.

We now check first whether to chain a `Future<T>` to another
future, and only does so if the latter future is a `Future<T>`
(or it's not a `T`, which shouldn't happen,
but currently does in some places).

Add test for behavior.

Lasse Reichstein Holst Nielsen 8129c40c5e Update LinkedList.contains to take advantage of internal structure.
Made it explicit in the documentation that elements of the `LinkedList`
are compared using identity, not `operator==`, even if they choose to
override that.
The linked list entries are directly linked to their containing list,
which is what defined their containing list. Merely being equal to an entry
of a list does not make another entry belong to that list.

The `contains` method now simply checks that the `list` property of the
the provided entry is the list itself, which matches the existing behavior
of `remove`.

Fixes #44189.

Srujan Gaddam 4cd0926703 [package:js] Add/modify tests for JS interop subtyping
Adds some basic tests to check for runtime subtyping with JS
interop types. Uses function types only to check for subtyping
relationships. Extends some tests on is and as checks as well.

Liam Appelbe f25c50fdcb [wasm] Use wasm traps to handle exceptions
The Dart exception is converted to a string, stored in a trap which
is passed through wasm, then converted back to a Dart exception.

Module instantiation can also throw a trap, because it internally
invokes the initialization function, if the module defines one. So I'm
handling this too.

Also, update to the new version of the wasm C API, which replaces some
foo_t** with foo_vec_t*.

Srujan Gaddam ed009afc4c [package:js] Add static errors for invalid extends
Bug: https://github.com/dart-lang/sdk/issues/37896

dart2js disallows JS interop classes from extending Dart classes,
and ddc does not work as expected. Dart classes that extends JS
interop classes can't be declared in ddc and throw an error on
usage in dart2js. This CL adds static errors for both cases.

Liam Appelbe e2840ed07a [wasm] Basic WASI support.
Enabling WASI when building an instance sets up the default WASI
imports, and can optionally capture stdout/stderr. I'd like to set up
something similar for stdin, but Wasmer doesn't support that yet.

I also improved error handling in WasmRuntime by adding Wasmer's last
error to the thrown exceptions where appropriate.

Lasse R.H. Nielsen a15025fc85 Harden StreamIterator against out-of-order events.
Users have seen event being sent *during* the `listen` call
to the underlying stream. This caught the `StreamIterator`
in an unanticipated state (subscription wasn't available yet).

Sending events during a `listen` call can currently happen
using a synchronous broadcast stream controller adding
events in the `onListen` callback.
That should be fixed so that broadcast stream subscriptions
are treated as paused during the `onListen` call like
single-subscription streams already are.

This change hardens the class against that particular malpratice,
but it's still possible to get into inconsistent states if the
`listen` call somehow manages to call back into the same
stream-iterator again. So, don't do that.

(The class also assumes that no stream will send events/call callbacks
* while paused.
* after cancelling
* after a done event
* while delivering another event.

If a stream does so, things will still crash.
It is believed that no platform stream will do any of these.)

Fixes #43779.
