For Instance, the WebAssemblyInstanceImpl function got inlined, as
there was only one caller, and it made setting the prototype

08f16d44b3 [wasm][pku] Assert write protection in strategic places
This adds a few DCHECKs to ensure that the process-wide memory
protection key is not writable (per thread) in a few strategic places:
- Before switching it to writable (which implicitly checks the initial
    state),
- when entering compiled code, and
- in the explicit unit test.

f7ac5a2978 [wasm-simd][liftoff] Fix i64x2.mul codegen bug
When dst != lhs, we moved lhs to dst, but dst can be == rhs, so we would
overwrite rhs, and end up comparing lhs with itself, always returning
false. We handle the different aliasing cases in the macro-assembler
function I64x2GtS, to simplify the checks in Liftoff a little bit.
TurboFan does not need to change as it will require dst == lhs when AVX
is not supported.

790e1dfe62 [snapshot] Don't create a fresh global in Context::New if no template was specified
This means we don't need to copy over properties, and accessors stay in
place similar to when we deserialize a custom snapshot.

This slightly changes the semantics of Context::New, so let's see
whether someone depends on this behaviour. We may need to revert if so
(hopefully until we can update the embedder).

159e440d4d [wasm][eh] Fix interpreter delegate in catch block
The recent change in the delegate semantics was incorrectly implemented
in the interpreter. It only checked that the first opcode of the target
block is a 'try': we also need to skip try blocks when we are already in
their 'catch' or 'catch_all' sub-block.
Use the exception_stack instead, since it already only contains indices
of try blocks that haven't reached their handlers yet.

71df28cb63 [x64] Optimize F64x2PromoteLowF32x4 with S128Load64Zero
When the input to F64x2PromoteLowF32x4 is a S128Load64Zero, we can skip
the load + promote, and promote directly with a memory operand. The
tricky bit here is that on systems that rely on OOB trap handling, the
load is not eliminatable, so we always visit the S128Load64Zero, even
though after instruction-selector pattern-matching, it is unused. We
mark it as defined to skip visiting it, only if we matched it.

367f86de7e [traphandler] Add arm64 simulator support on Windows
This ports the trap handler implementation for the arm64 simulator
from POSIX to Windows. Apart from different registers being used
for passing parameters, and different access to these register
values in the signal handler, the implementation is exactly the same.

The new logic is being used for sanitizer builds which automatically
target arm64 via the simulator, or if manually compiling an arm64
simulator build on x64. I manually tested the latter.

Also, the existing unit test is enabled for Mac (which was missing)
and Windows now.

833b3c96a6 [inspector] Make ArrayBuffer.[[ArrayBufferData]] deterministic.
Previously the internal `[[ArrayBufferData]]` property for `ArrayBuffer`
objects reported by the inspector (and used by the DevTools front-end to
identify `ArrayBuffer`s and `WebAssembly.Memory`s using the same backing
store) simply contained a hex string representation of the backing store
pointer. However that unnecessarily leaks internal addresses and more
importantly is not deterministic, which complicates tests (just blew up
on layout tests).

This CL introduces an automatically incremented `BackingStore::id()`,
which is used instead now and is deterministic.

table type is externref. With this CL V8 handles the JavaScript case
spec-compliant.

5a7d7de9e2 [wasm-gc][turbofan] Speculative direct calls for call_ref
Behind the --wasm-inlining flag, we introduce speculative direct calls
as an alternative to invoking functions through references.
In pseudocode, call_ref(func_ref, args...) reduces to
  if (func_ref == function_reference_at(expected_index)) {
    call_direct(expected_index, args...)
  } else call_ref(func_ref, args...)
The introduced direct call can later get inlined in WasmInliningPhase.
Currently, we always speculate that the reference is the function at
index 0. Proper heuristics, based on liftoff runtime feedback, will come
later.

b8146576d6 Reland "[test] Avoid disabling of RCS during runtime"
This is a reland of 11045926ca

The first version of this CL uncovered a TSAN failure when not disabling
RCS anymore. The problem was that a background thread was still updating
RCS counters, while the main thread already dumped those values during
tear down. This CL fixes this by dumping counters only after all
background threads are stopped.

Original change's description:
> [test] Avoid disabling of RCS during runtime
>
> Test was flaky since disabling of RCS at runtime is unsafe. Some code
> (e.g. TRACE_GC) is run only in case RCS is enabled and such code paths
> might also DCHECK that RCS is enabled.
> A background thread (sweeping in this case) could've already
> entered such a code path right before RCS is disabled. In this case the
> guard at the entry still saw that RCS is enabled but subsequent DCHECKs
> that ensure that RCS is enabled might fail.
>
> We could fix this by completing the sweeper tasks before disabling RCS
> but there might be other similar tasks which might be run at that point
> in the future (e.g. memory unmapper).
>
> Disabling the flag doesn't even seem to be needed for the initial
> regression test, so it seems simpler to just not disable RCS anymore.
