efd42d689f [turbofan] Do not optimize Trap with siblings inside If
Trying to optimize in such case breaks down the optimization, as we
end up with potentially non-eliminatable nodes that depend on the dead
IfTrue/IfFalse node.
Drive-by: Clean up dead nodes with {Kill()}.

75c130a862 cppgc: Allow writes to dead slots in member assignment checks.
The checks for assignemnts to member during prefinalizers assumed the
slot has to live. It was assumed that if a slot is dead then we would
not be updating it.
Prefinalizers are allowed to touch dead objects and thus are techincally
allowed to write to dead slots. Such writes are usually redundant (the
object will be swept soon anyway) but are not always easy to get rid of.

749e41d468 [fuzzer] ref.func should look up functions by signature
When we generate identical signatures in the fuzzer,
we generate one function for each of the copies.
However, when these functions are added to WasmModulBuilder,
all will be assigned the same signature index.
Therefore, when ref.func tries to find a function corresponding
to a signature index, it will fail, despite a matching signature
existing in the module.
This CL fixes this issue by looking up functions by signature
over signature index.

6d25f20f35 [debug] Set breakpoints correctly right after function literals.
The logic to locate the correct function to set a breakpoint in based
on script position was treating SharedFunctionInfo::EndPosition() as
inclusive rather than exclusive. There are various assumptions all over
the Debugger that seem to demand this treatment for the toplevel script.
But it's definitely wrong for function literals.

0195a5eb49 [inspector] Consistently treat promise rejections as side-effecting.
Previously we'd treat %_AsyncFunctionReject (and %AsyncFunctionReject)
as side-effect free (in async functions), but that's not correct, since
promise rejections have side-effects (at the very least triggering the
unhandled promise rejection machinery in the browser).

This required a minor refactoring as previously we'd classify functions
as side-effecting or not depending on whether they contain any calls to
side-effecting intrinsics, no matter whether this call is actually
executed or not. That would break REPL mode however if we'd generally
treat all async functions with %_AsyncFunctionReject intrinsic calls as
side-effecting, so instead of performing the intrinsic checks ahead of
time, we now perform the test at execution time.

29afe1e585 [turbofan] Optimize traps after Merge/IfTrue/IfFalse
We implement two optimizations for trap conditionals for patterns that
come up in wasm-gc.
In case of a Merge followed by a trap, where the path conditions of all
branches of the Merge contain the trap condition, we lift the trap into
the branches of the Merge.
In case of a Branch whose IfTrue branch is followed by a TrapIf with the
same condition, we replace it with the trap followed by the IfFalse
branch. Symmetrically for IfFalse and TrapUnless.

25f0e32915 [torque] Make return types required
Currently, it is possible to declare macros, builtins, etc., without
specifying a return type, in which case the return type is treated as
void. This is confusing; the code is more clear if we require the return
type to be specified.

Aside from src/torque, this change is almost entirely just adding
`: void` until the compiler is happy. However, two intrinsics in
src/builtins/torque-internal.tq have been corrected to declare an
appropriate return type. Those two intrinsics were only used in code
generated within the compiler after the type-checking phase, so we never
noticed that their return types were declared incorrectly.

2cbcf6e089 [wasm] Remove process-wide address space limit
The address space limit puts an arbitrary cap on the total reservation
size, thus limiting the total number of Wasm memories to around 100 on

Since the usable address space on 64 bit is much larger than the
1TB+4GB limit, this makes us reject code that we could otherwise just
execute.

This CL thus removes that limit completely.

d6c01059a5 [inspector] Align async task frame reporting for await.
The V8 Inspector was sending an additional frame as part of async stack
traces for async functions, which pointed to the first executed `await`
in the async function. This is leaking an implementation detail of how
(and more precisely when) the inspector decides to collect this stack
trace. From the users perspective the async part of the stack trace is
supposed to capture what happened _prior to the task_ - meaning in case
of async functions: What lead to the execution of the async function.
This is reflected by the fact that the DevTools front-end (and the V8
Inspector itself) performs post-processing on these async call stacks,
removing the misleading top frame from it. But this post-processing is
not applied consistently to all async stack traces (i.e. the Console
message stack traces don't get this), and potentially also not applied
consistently across consumers of the Chromium debugger backend.

Instead the V8 Inspector now removes the top frame itself and thus
reports `await` consistently with how other async tasks are reported to
debugger front-ends.

Note: This preserves backwards compatibility with old versions of
devtools-frontend, which do post-processing (for the Call Stack) only on
async stack traces marked with "async function", while we now mark these
async stack traces with "await" instead (aligned with what the front-end
is using as user visibile string anyways in the Call Stack section, and
this matching will be updated in a separate follow up CL to look for
"await" instead of "async function").

4b6ee11532 [asm] Fix importing monkey-patched objects
This fixes a long-standing TODO to disallow importing receivers that
have "toString" or "valueOf" patched. Calling those methods could have
observable side effects, so allowing that would require bigger
refactorings to ensure that we only call each such function exactly once
per import, and in the right order.
Since this use case is rare, we just forbid importing such receivers.

77906a700c [regexp] Hide the generic JSRegExp::DataAt/SetDataAt accessors
.. and refactor js-regexp.h.

- Hide the generic DataAt/SetDataAt accessors and replace them by
  dedicated accessors. Use the common lower_case naming scheme for
  these.
- Shuffle around definitions in js-regexp.h s.t. they are in a
  meaningful order.
- Dedupe the source/flags accessors - these fields are stored both
  on the instance and on the data array. We keep only accessors for
  the instance. Previously, these were disambiguated through naming
  oddities (e.g. Pattern() returned data->source).

37430ba3f8 [wasm] Move misplaced DCHECK in wasm interpreter
When handling the 'end' opcode, there was a confusion with the value of
"unreachable". This DCHECK assumes the value of "unreachable" before
closing the scope, but was placed after the value is potentially updated
to reflect the state after the 'end' opcode.

7d849870ff [regexp] Reorganize and deduplicate in the regexp parser
The parser is organized in a somewhat tricky way s.t. it can be
hard to map the implementation back to the specified grammar.

In particular, the logic for CharacterClassEscape, ClassEscape,
and CharacterEscape was implemented twice - once inside a character
class, once outside.

This CL refactors related logic to have only a single implementation.

As a drive-by, fix one related inconsistency related to \k inside
a character class.

d7fc0134ee [cleanup][test] Don't rely on __COUNTER__ in expectations
Several of the cctest/test-bytecode-generator/* tests used to rely
on the __COUNTER__ C++ compiler macro, which could cause spurious
test failures due to mismatched expectations when usages of that
macro were added or removed elsewhere in the code. This patch switches
to a custom, controllable static counter variable instead, to make
the tests' behaviors self-contained.

a0ace8a8a5 [wasm] Interpret table.grow result as 32 bit
In Liftoff, the result of table.grow was smi-untagged and sign-extended
to a ptr-sized value. However the result is typed as i32, so the upper
32 bits should be cleared on 64 bit platforms. In particular this is
observable when the value is used as an index for a memory operand,
which leads to the repro in the attached issue.

Match the TF behavior by untagging the value as a 32-bit int.

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.

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.

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.

e366c4b7d4 [wasm][test] CFI also prints UBSan errors
Instead of trying to detect which sanitizer we run on, just allow the
output that any sanitizer would produce.
Note that the regular expression syntax is pretty limited, so we cannot
express this as a single regex.

This removes the single use of {V8_USE_UNDEFINED_BEHAVIOR_SANITIZER}
again, but for completeness I leave it in {macros.h} for now.

0af529a365 [wasm] Change type() for js-api objects
The type() function is now part of the js-api object and not part of the
constructor anymore, see
https://github.com/WebAssembly/js-types/blob/master/document/js-api/index.bs#L971

This fixes a failing spec test, but there is a bug in the test itself,
so it cannot be enabled yet.

11045926ca [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.

bc3b9332ac [wasm-gc] Implement nominal types
Per https://github.com/WebAssembly/gc/issues/234, this implements
"nominal" type definitions with explicit supertypes, and statically
typed RTT-less instructions for allocation and testing/casting.
This should be fully backwards compatible with existing Wasm modules.
