This change is almost trivial. The closure is stored on the callback's
RawReceivePort, not in the VM. So we can basically just remove the CFE
check and it pretty much works. The only problem is that we can't set
function.FfiCallbackTarget anymore, so most of the CL is dealing with
that.
A few places were deciding whether an FFI trampoline was a call or a
callback based on whether function.FfiCallbackTarget() was null. But
now the target will be null for async callbacks. So instead I've added
a new value to the FfiCallbackKind enum (and renamed it), and changed
those checks.
Sync callback closures will be a separate CL, because they're more
complicated.

Following the refactoring we started in previous CLs, this splits string
and int patch files into (1) patch files that only patch and don't add
implementation classes (2) files for implementation classes (3) helpers.
Changes:
- `string_patch` is split into `string.dart` and `string_patch.dart`.
- VM's `integers_patch.dart` copied as `int_patch.dart` and updated.
This was needed as `integers_patch` requires VM's library paths in
imports.
We needed to copy this file to be able to optimize based on
dart2wasm's implementation classes. However in this CL we copy the
file as-is and update import paths.
- VM's `string_buffer_patch.dart` copied to be able to use the string
implementation classes from the new library.
`string_buffer_create.dart` is merged ino `string_buffer_patch.dart`.
- `getHash` and `setHash` to set object identity moved to
`object_helper.dart`, to be able to use in string implementations.
- Redundant `new` keywords in copied files removed.
One TODO added in `string_buffer_patch.dart` when allocating a new
string to the buffer:
// _parts = _GrowableList.withCapacity(10)..add(str);
// TODO(omersa): Uncomment the line above after moving list
// implementations to a library.
_parts = [str];
We can enable the old code again after moving list implementations to a
library.

Several locations in the core SDK contain `!` or `?.` operations that
will become unnecessary once the language feature `inference-update-2`
(which provides field promotion) is enabled. For example, in this
method from the class `_IOOverridesScope`, `_previous` refers to a
private final field, so after field promotion is enabled, the test `if
(_previous != null)` will promote it, and the `!` in
`_previous!.createDirectory` will become unnecessary:
Directory createDirectory(String path) {
if (_createDirectory != null) return _createDirectory!(path);
if (_previous != null) return _previous!.createDirectory(path);
return super.createDirectory(path);
}
Since the SDK is built in a mode where warnings like this result in
build failures, we need to temporarily change the logic into a form
where the same promotion effect is achieved through local variable
type promotion:
Directory createDirectory(String path) {
if (_createDirectory != null) return _createDirectory!(path);
var previous = _previous;
if (previous != null) return previous.createDirectory(path);
return super.createDirectory(path);
}
(Note that `_createDirectory` doesn't need to change, because it is a
non-final field, so it won't undergo promotion).
After `interface-update-2` has been enabled, I will make a follow-up
CL that removes the local variables and simply takes advantage of
field promotion, e.g.:
Directory createDirectory(String path) {
if (_createDirectory != null) return _createDirectory!(path);
if (_previous != null) return _previous.createDirectory(path);
return super.createDirectory(path);
}
Note: in theory it would be possible to do all this in a single step,
by atomically enabling field promotion and changing the SDK in the
same CL. However, I prefer breaking it up into stages like this,
because the act of flipping a langauge flag on tends to have
wide-ranging consequences, so I want the CL that does the flip to be
as small as possible.

New typed data implementation that optimizes the common cases.
This uses the best possible representation for the fast case with a
representation like:
class _I32List implements Int32List {
final WasmIntArray<WasmI32> _data;
int operator [](int index) {
// range check
return _data.read(index);
}
void operator []=(int index, int value) {
// range check
_data.writeSigned(index, value);
}
...
}
This gives us the best possible runtime performance in the common cases
of:
- The list is used directly.
- The list is used via a view of the same Wasm element type (e.g. a
`Uint32List` view of a `Int32List`) and with aligned byte offset.
All other classes (`ByteBuffer`, `ByteData`, and view classes)
implemented to be able to support this representation.
Summary of classes:
- One list class per Dart typed data list, with the matching Wasm array
as the buffer (as shown in the example above): `_I8List`, `_U8List`,
`_U8ClampedList`, `_I16List`, `_U16List`, ...
- One list class per Dart typed data list, with mismatching Wasm array
as the buffer. These classes are used when a view is created from a
list, and the original list has a Wasm array with different element
type than the view needs. `_SlowI8List`, `_SlowU8List`, ...
These classes use `ByteData` interface to update the buffer.
- One list class for each of the classes listed above, for immutable
views. `_UnmodifiableI32List`, `_UnmodifiableSlowU64List`, ...
These classes inherit from their modifiable list classes and override
update methods using a mixin.
- One `ByteData` class for each Wasm array type: `_I8ByteData`,
`_I16ByteData`,
...
- One immutable `ByteData` view for each `ByteData` class.
- One `ByteBuffer` class for each Wasm array type: `_I8ByteBuffer`,
`_I16ByteBuffer`, ...
- A single `ByteBuffer` class for the immutable view of a byte buffer.
We don't need one immutable `ByteBuffer` view class per Wasm array
type as `ByteBuffer` API does not provide direct access to the buffer.
Other optimizations:
- `setRange` now uses `array.copy` when possible, which causes a huge
performance win in some benchmarks.
- The new implementation is pure Dart and needs no support or special
cases from the compiler other than the Wasm array type support and
intrinsics like `array.copy`. As a result this removes a bunch of
`entry-point` pragmas and significantly reduces code size in some
cases.
Other changes:
- Patch and implementation files for typed data and SIMD types are split
into separate files. `typed_data_patch.dart` and `simd_patch.dart` now
only contains patched factories. Implementation classes are moved to
`typed_data.dart` and `simd.dart` as libraries `dart:_typed_data` and
`dart:_simd`.
Benchmark results:
This CL significantly improves common cases. New implementation is only
slower than the current implementation when a view uses a Wasm array
type with incompatible element type (for example, `Uint32List` created
from a `Uint64List`).
These cases can still be improved by overriding the relevant `ByteData`
methods. For example, in the example of `Uint32List` view of a
`Uint64List`, by overriding `_I64ByteData.getUint32` to do a single read
then requested bytes don't cross element boundaries in the Wasm array.
These optimizations are left as future work.

The purpose of the wasm_js_compatibility target is to facilitate experiments with a JS compatibility mode for Dart2Wasm. Initially, we're just going to focus on typed data, but this will give us a place to experiment with moving List and String to JS as well.
In addition, someday down the road we hope to experiment with two additional compatibility changes:
1) Exclusively using double for all Dart numbers
2) Allowing undefined to flow as null.
The two major benefits of this approach are:
1) Much faster JS interop
2) To make it easier to bring up Dart2JS applications on Dart2Wasm
The only downside will be access overhead on the Wasm side, but the JS builtins proposal could potentially bring us close to parity with Wasm builtins someday.
Tested: Wasm specific trivial refactor.

Right now `utf8.encode()` has a static return type of `List<int>`
due to extending `Encoding` (which extends `Codec<String, List<int>>`).
We cannot easily change `Encoding` to extend `Codec<String, Uint8List>`
because that would also change `utf8.decode()` to require `Uint8List`
which would be a breaking change.
So instead we override `utf8.encode()` to have more precise return type.
Some parts of our SDK are run using the checked-in SDK, so it cannot
rely on the changed return type yet (until checked-in SDK is rolled).
So we use `const Utf8Encoder().convert()` as a temporary change, as
that already has `Uint8List` return type.

The iterable is used for the `keys` and `values` of `LinkedHashMap`.
The original code remembered the internal data list and used-count
when the iterable was created, and if the iterable was modified
between creating and iterating, the iterated values would not match
the map.
The solution is to not cache those values, and read them from the
hash table when creting the `Iterator` instead.

The main contribution of this CL is unification of disparate
handling of various functions like `Future.timeout`,
`Future.wait`, `_SuspendState.createAsyncCallbacks` and
`_SuspendState._createAsyncStarCallback` into a single
`@pragma('vm:awaiter-link')` which allows Dart developers
to specify where awaiter unwinder should look for the next
awaiter.
For example this allows unwinding to succeed for the code like this:
Future<int> outer(Future<int> inner) {
@pragma('vm:awaiter-link')
final completer = Completer<int>();
inner.then((v) => completer.complete(v));
return completer.future;
}
This refactoring also ensures that we preserve information
(including Function & Code objects) required for awaiter
unwinding across all modes (JIT, AOT and AOT with DWARF stack
traces). This guarantees users will get the same information
no matter which mode they are running in. Previously
we have been disabling awaiter_stacks tests in some AOT
modes - which led to regressions in the quality of produced
stacks.
This CL also cleans up relationship between debugger and awaiter
stack returned by StackTrace.current - which makes stack trace
displayed by debugger (used for stepping out and determinining
whether exception is caught or not) and `StackTrace.current`
consistent.
Finally we make one user visible change to the stack trace:
awaiter stack will no always include intermediate listeners
created through `Future.then`. Previously we would sometimes
include these listeners at the tail of the stack trace,
which was inconsistent.
Ultimately this means that code like this:
Future<int> inner() async {
await null; // asynchronous gap
print(StackTrace.current); // (*)
return 0;
}
Future<int> outer() async {
int process(int v) {
return v + 1;
}
return await inner().then(process);
}
void main() async {
await outer();
}
Produces stack trace like this:
inner
<asynchronous suspension>
outer.process
<asynchronous suspension>
outer
<asynchronous suspension>
main
<asynchronous suspension>
And when stepping out of `inner` execution will stop at `outer.process`
first and the next step out will bring execution to `outer` next.

Original change's description:
> [dart:html] Move NullWindowException to implementation
>
> Window.open may open a null window in more cases than expected.
> Users may not care that the window they get back is invalid if
> they never use it. Therefore, this CL moves the exception to
> the implementation of the returned window in order to reduce
> noise, but still give a way for users to recover if they wish
> to do so.
