These classes were introduced only because `_ZoneFunction`
could not take a generic type argument at the time.
It can now.

This adds a --platform= option to dart2wasm to read the SDK libraries
from that dill file instead of compiling them from source every time.
If the option is not given, the SDK libraries are compiled, like before.
Also adds a "dart2wasm" build target, which will build the dart2wasm
platform dill and compile dart2wasm to two AOT snapshots (with and
without asserts). The dart2wasm scripts in sdk/bin are updated to run
via these snapshots and use this platform dill.
This speeds up test runs for the dart2wasm-hostasserts-linux-x64-d8
configuration by approximately 45x.

This null char is inserted by _toNullTerminatedUtf8Array, and right
below that function is _toStringFromUtf8Array, which does the opposite.
But _toStringFromUtf8Array is currently dead code, so it looks like the
intent was always to use _toStringFromUtf8Array for this, and the fact
that utf8.decode was being used instead is just a mistake.

Users are getting confused by `allocate` and `call` in the `Allocator`s.
This CL clarifies the behavior by extending the documentation.
Unfortunately, we cannot expose the actual implementation of `call`. All
calls to `sizeOf<T>()` must have `T` as compile-time constants. So,
instead of `call` having a body in Dart, all call-sites get the behavior
inlined (`x.call<Int32>(3)` is transformed to
`x.allocate<Int32>(sizeOf<Int32>() * 3)`).

The new implementation moves away from desugaring of async
functions on kernel AST, state machine generated in the flow graph and
capturing all local variables in the context.
Instead, async/await is implemented using a few stubs
(InitSuspendableFunction, Suspend, Resume, Return and
AsyncExceptionHandler). The stubs are implemented in a
platform-independent way using (macro-)assembler helpers.
When suspending a function, its frame is copied into a SuspendState
object, and when resuming a function it is copied back onto the stack.
No extra code is generated for accessing local variables.
Callback closures are created lazily on the first await.
Design doc: go/compact-async-await.

This fixes an issue where VM would run the async* generator after a
`yield` / `yield*` even though the subscription may be paused or
cancelled.
Furthermore this fixes an issue where `StackTrace.current` used
in async* generator crashes VM and/or produces truncated stack
trace.
This fixes the following existing tests that were failing before:
* co19/Language/Statements/Yield_and_Yield_Each/Yield_Each/execution_async_t08
* co19/Language/Statements/Yield_and_Yield_Each/Yield_Each/execution_async_t09
* co19/Language/Statements/Yield_and_Yield_Each/Yield_Each/execution_async_t10

The `toString` used the sign of `hours` to get a leading `-`
when the duration is negative. However, a negative duration of
less than one hour would therefore miss out on the sign,
because `-0` is not an integer.
Now handles sign explicitly.
Fixes#48841.
