Currently hash code for a closure is the hash code of it's runtime type.
This causes a lot hash collisions in some apps and cause performance
issues.
With this patch we now use captured objects in closures when calculating
hash codes.
The hash codes are now:
- For tear-offs:
mix(receiver hash, closure runtime type hash)
- For instantiations:
mix(instantiated closure hash,
hashes of captured types)
Note that an instantiation can be of a tear-off, in which case
"instantiated closure hash" will calculate the tear-off hash as above.
- For others (function literals, static functions), the hash is the
identity hash.
Fixes#54912.

If a target `_Future` is chained to another source `_Future`,
then it's because the target will complete with the same
result as the source future. Instead of keeping both
alive with a listener on the source which completes the target,
instead the target moves all its listeners to be directly on
the source, and keeps a link to the source in case more listeners
are added later.
The idea is that most futures are unreferenced after they have
had their first listener, so the target future has a chance
to be GC'ed.
If the target future has `.ignore()` called, and has no listener,
then the source completing with an error should not cause the
error to be uncaught. Without the optimization, the source would
have had a listener, and the target would ignore the error.
To simulate that, the source now gets a copy of the target's
`_ignoreUnhandledErrors` flag.
This is still not precisely the same as it would be without the
optimization. If *two* target futures are chained to the same source,
and only one of targes has `.ignore()` called, then this
implementation will make the uncaught error not be reported,
where it technically should.
(An alternative would be to *not* use chaining for futures
with `ignore()` called on them. But those are precisely futures
that are likely to be GC'able, because someone has already said
that they don't care if the future complete with errors.)

There is a performance impact in:
`stdout.lineTerminator = "\r\n";`
For small writes (<100 chars), the performance loss is lost in the noise of the `write` system call.
For writes of ~500 chars, the performance is about half of that without line terminator translation. But, on a M2 Mac laptop, ~80M characters can be written per second.

Improve the handling of code where the async flow forks:
e.g. for `fut.whenComplete(c.complete)` we might proceed
unwinding through awaiters of `c.future` and forget about the
future returned from `whenComplete`. This happens because
we choose to present result of the unwinding as a single
stack and not a tree. In this situation the error will only
propagate into that future and whether or not the error will be
handled depends on that future alone.
As part of this change also start respecting ignored bit on
futures without listeners.

This CL adds @pragma('vm:awaiter-link') in various places in
Stream implementation to facilitate unwinding and expands
async unwinding logic with more information about
Stream internals.
At the same time be more conservative when checking if an
exception thrown from async method handled: failing to unwind
the stack fully creates situations when we incorrectly report
caught exceptions as uncaught, which frustrates users.
To distinguish stream subscriptions with and without error
handlers we add a state bit. Otherwise, it looks like all
subscriptions have error handlers because if no error
handler is installed we eagerly install error handler forwarding
the error to `Zone.handleUncaughtError`.

The dart closures for the then/onError callbacks we use on a JS promise
will not flow back into dart. There's therefore no reason to use the
very heavyweight `allowInterop` mechanism.
This makes (after [0]) asynchronous calls to JS from Dart more than 2x
as fast.
This also aligns the `promiseToFuture` implementation with the extension on
`JSPromise` (see sdk/lib/_internal/wasm/lib/js_interop_patch.dart)
modulo the fact that the API doesn't work on interop types but Dart
types and needs therefore the full JS<->Dart conversion.
=> Maybe it would make sense to deprecate `promiseToFuture` / not offer it
in dart2wasm and make users use instead the extension on `JSPromise`
instead?

The type category table is a O(number-of-classes) sized byte array that
maps from class-id to either a type category (function, record, ...) or
a masqueraded class-id.
* for flute this table takes up around 1 KB.
* this prevents from making concrete class-ids come before all abstract
class ids
After recent changes the core RTT implementation no longer involves
masqueraded types (i.e. `<obj> is/as <type>` and `<type> <: <type>`
queries don't trigger masquerading functionality)
This CL removes the type category table, the special casing in the
class-id assignment and the compiler support for building the table.
Instead we move the logic to pure dart code, which can use normal `is`
checks to perform its function.
We add one optimization: The compiler will provide the class-id from
which one only non-masqueraded classes come. This makes the masquerading
function have a fast path.
* We use `Wasm{TypedData,String}Base` marker interfaces i
`dart:_internal` to check for wasm-backed implementations
* We use `-Ddart.wasm.js_compatibility` to provide JSCM mode
We add a test that actually exercises the 2 modes.

- Since "Futures", "Streams", and "Zones" are plural and not in code syntax, can make them lowercase to be consistent with the `dart:core` entry in the same list.
- Use the full "platform interopability" term when introducing the libraries, as it might be a newer term for readers.
- Replaces "interoping" term as after searching it seems not common and easily mistaken.
- Fixes spelling of "function"

FFI loads and stores via structs can have a TypedData as receiver,
so this CL updates those loads to `kMayBeInnerPointer`.
This CL adds an IL test to verify that for `Pointer` loads the untagged
value is treated correctly as `kCannotBeInnerPointer`.
(And adds some prefer-inline pragmas to make some common operations
be inlined to avoid allocating `Pointer` objects.)
This CL updates the load in the FFI closures to use a load-field.
This can also potentially enable not allocating a pointer object when
this closure is inlined.

CoreLibraryReviewExempt: Only adding some pragmas.

Analyzer fix https://github.com/dart-lang/sdk/issues/54754 has
landed. A new version of package:analyzer and package:dartdoc have
been released. `pub global activate dartdoc` should now work.
Patchset 1 is identical to the original CL.
The only difference is an extra test testing with negative offsets.
=== Original CL description ===
Structs and unions can now be created from an existing typed data
with the new `create` methods.
The typed data argument to these `create` methods is optional. If
the typed data argument is omitted, a new typed data of the right
size will be allocated.
Compound field reads and writes are unchecked. (These are
TypedDataBase loads and stores, rather than TypedData loads and stores.
And Pointers have no byte length.) Therefore the `create` method taking
existing TypedData objects check whether the length in bytes it at
least the size of the compound.
