Add a --deopt-to-baseline flag, on by default, which allows returning to
sparkplug code when deoptimizing.
However when we turn this off, no longer deoptimizing to baseline code
means we can omit marking most bytecodes as valid jump targets. Leaving
just OSR and exception handling entry points.
This reduces the baseline code size by ~18% on Arm64.

With the old API, wrapping an import and export with JS Promise

With streaming compilation we delay the generation of errors until after
all bytes are received, so that potentially better error messages get
generated. With this CL we also delay the generation of errors in the
combination of lazy compilation and streaming compilation.
In particular, this CL does the following:
* It avoids the creation of a `DecodeFail` task in
`FinishAsyncCompileJobWithError`, which would create an error immediately before a potential name section arrived.
* It calls `CompilationStateImpl::SetError()` so that an error is
created once the stream finishes.
* It removes the return value of `ProcessFunctionBody` so that wire
bytes continue to be received even after a validation error.
* It adds an early exit to `ProcessFunctionBody` if
`CompilationStateImpl::failed()` is true, so that we don't continue
validation after the first detected error.

The serialized module contains information for each function whether the
serialized code for the function exists, and whether the function has
been executed before serialization. The latter information is used to
decide if the function should get compiled eagerly after deserialization
(in case the function has been executed before serialization), or if the
function should get compiled lazily because it will probably not be
executed anytime soon.
So far this code only worked for eager compilation. When lazy compilation
was enabled, all functions would get compiled lazily after
deserialization. With this CL the behavior described above is extended to
lazy compilation.

If we grow memory (out-of-place, so only without trap handling and only
if the maximum is >1GB) and the previous size is close to the maximum,
then the minimum growth we calculate can be bigger than the allowed
maximum. In this situation, the {std::clamp} has undefined behaviour,
since the provided lower limit is bigger then the upper limit.
Thus apply {std::min} and {std::max} in an order such that {max_pages}
has precedence over {min_growth}.

Currently, we canonicalize types for call_indirect by looking in the
current module for a signature of the same shape. This is not enough
as of wasm-gc. Instead, the canonical identifier representing a type
has to be computed via isorecursive canonicalization.
This change is implemented behind a flag for now.
Future work: Also integrate export wrappers with isorecursive
canonical types. We need to store wrappers in instance-independent
storage.
Drive-by:
- Always emit type check for call_indirect. We did not emit a check
only when typed-function-references was enabled, but not gc. This
is not something that will be possible long-term.
- Fix some wasm cctests.

This adds a bunch of tracing hooks to the module decoder and uses
them to support "annotated hexdump" output for full modules in wami:

- Removed duplication and unnecessary indirection from all suites testcfgs.
- Introduced a more comprehensive context to cover both command context and other platform specific concerns.
- Propagated above context to TestLoader to allow for test counting command execution on all platforms.
- Wrapped original pool with another class to give it a new interface and allow injecting different implementations in the future.
- Consolidated progress indicators under a single processor in the pipeline.
- Consolidated result retention requirements calculation outside of pipeline chain.
- Refactored LoaderProc and got it under tests.
- Added some more tests for the standard runner.
- Extracted BuildConfig class.

Currently the same reduction is used for both TypedArray's and
DataView's byte{Length,Offset} accessors. But their behavior differ on
detached buffers: TypedArray returns 0 while DataView throw.
Do not do the optimization for DataViews if we can't depend on the
detach protector.

By about 10x-20x depending on platform and configuration.
Shorter test strings make the set of all possible substrings

TSAN may cause the sandbox to fail to obtain enough virtual address
space during initialization, thereby causing it to fall back to a
smaller backing reservation. This may then in turn cause future
WebAssembly.Memory allocations to fail.

With the flag --always-use-forwarding-table we could end up turning a
String into a ThinString that had a forwarding index set.
This could happen when a String with a forwarding index is externalized.

Suspender.{returnPromiseOnSuspend,suspendOnReturnedPromise}
are not tied to a specific suspender anymore, so move them to
WebAssembly.{returnPRomiseOnSuspend,suspendOnReturnedPromise}.
With this change, the suspender property is not needed anymore on the
function data. Convert it to a boolean flag that just indicates whether
a function uses the JS Promise Integration API.

This CL is the first step towards the 'static API':
https://github.com/WebAssembly/js-promise-integration/pull/1/files
The limitation of the previous API is that the stack-switching wrappers
are tied to a particular suspender. Since a suspender cannot be
re-entered until the corresponding computation has completed, this
prevents creating multiple concurrent instances of the same export.
Multiple APIs have been proposed and are still under discussion to
solve that, but the core idea is the same: the suspender should become a
runtime argument of the export and the import. This CL implements that.
For now, the suspender is still explicit everywhere: it is created in JS
and passed to the export, and forwarded to the JS import. Eventually,
the suspender may be completely hidden from JS: it would be materialized
by the export wrapper, and "swallowed" by the import wrapper, as
proposed in the PR above.
