Original CL in patchset 1.
Fix for simdbc in patchset 4.
Fix for arm32 precompiled in: https://dart-review.googlesource.com/c/sdk/+/120660/
This CL optimizes Pointer operations in hot loops for Pointer<NativeInteger/NativeDouble/Pointer> (not for structs).
Design: go/dart-ffi-pointers-il
It provides roughly a 100x speedup for the FfiMemory benchmark. The next 5x speedup is to get rid of allocations due to `load` and `store` not being inlined.
FFI API is changed to enable optimizations:
* Disable dynamic invocations of Pointer.load / Pointer.store.
* Disallow implicit downcast of argument passed to Pointer.store.
* Stop zeroing out Pointer.address on Pointer.free().

Also remove reload check for deferred prefixes. This check was added to avoid behavior of library prefixes giving spurious "not loaded" errors after a reload, but now this error can never occur. Resolves a difference in reload between AST and bytecode modes, since bytecode mode isn't surfacing the deferred property.

TransferableTypedData instances are one-use kind of thing: once receiver materializes it, it can't be used
again, once sender sends it out to an isolate, sender can't send it to different isolate.
Example of use:
sender isolate:
```
Future<TransferableTypedData> consolidateHttpClientResponseBytes(HttpClientResponse response) {
final completer = Completer<TransferableTypedData>();
final chunks = <Uint8List>[];
response.listen((List<int> chunk) {
chunks.add(chunk);
}, onDone: () {
completer.complete(TransferableTypedData.fromList(chunks));
});
return completer.future;
}
...
sendPort.send(await consolidateHttpClientResponseBytes(response));
```
receiver isolate:
```
RawReceivePort port = RawReceivePort((TransferableTypedData transferable) {
Uint8List content = transferable.materialize().asUint8List();
...
});
```

See https://github.com/tc39/proposal-regexp-named-groups
for a high-level description of the feature and examples. This is one of the
features requested in https://github.com/dart-lang/sdk/issues/34935.
This is a partial implementation because while there is a way to retrieve
groups via Dart by name, it requires casting the returned Match to the
new RegExpMatch interface to avoid changing the RegExp interface.
Changing the RegExp interface will happen in a future update, since there
are other planned changes to the RegExp interface coming soon and that way
we only change it once. See https://github.com/dart-lang/sdk/issues/36171
for more details on the planned changes.
Also, since only BMP regular expressions are supported, not full
Unicode ones (i.e., those with the /u flag in ECMAscript), \k<NAME>
will only be parsed as a named back reference if there are named
captures in the string. Otherwise, the \k will be parsed as the identity
escape for backwards compatibility. The new tests illustrate this
difference.

This removes the 3 fields from the classes in Dart and instead describes
the layout in C++ via a RawTypedDataView class (as already do with
normal RawTypedData). The existing "semi" TypedDataView handle class is
changed to be a real handle class.
This decreases performance of some microbenchmarks due to field guards
not being used anymore (before the JIT could add a field guard to view classes
guarding that only normal typed data is used as backing store (and not e.g. external

In Dart2, type bounds checking is either performed by the common front-end or
by explicitly generated code, but not by type finalization or runtime anymore,
as it was done in Dart1.
Consequently, the class BoundedType is not needed anymore, and malbounded or
malformed types are not seen by the runtime either.

GrowableArrayMarker was a class that implemented int and was used to
enable implementation of default List factory constructor in pure Dart:
factory List([int length = GROWABLE_ARRAY_MARKER]) {
return identical(length, GROWABLE_ARRAY_MARKER) ? new _GrowableList<E>(0)
: new _List<E>(length);
}
Its existence complicated all kinds of things in the VM and it is finally
time to remove it.
Instead we build List factory body directly in IL.
This CL also provides inlining rule for `new List(n)` case.

Original change's description:
> [mirrors] Add IsolateMirror.loadUri.
>
> This allows a programmer to dynamically load code into an isolate. The closest existing API is Isolate.spawnUri, but communication with the dynamically loaded code in that case is limited to asynchronous message passing of JSON-like objects.

This optimization depends on an always-present Dart compiler, which is broken by the architecture of the CFE.
