40cef10f26 Reland "cppgc,heap: Implement atomic unified heap GC"
This is a reland of 539f0ed23b

The reland fixes creating TimeDelta from double which requires
saturated_cast<>. Improvements to this constructions are tracked
in v8:10620.

d8cd725f7b [nci] Implement missing generic lowering bits
... for nci code, in which several phases of the compiler are not
active:

LowerJSCreateCatchContext
LowerJSCreateEmptyLiteralObject
LowerJSCreateIterResultObject
LowerJSCreateWithContext
LowerJSGetIterator
LowerJSGetTemplateObject

With this change, the nci variant passes the test suite. Tests
relying on turbofan-specific behavior (e.g. deopts) are skipped.

c65c1c10a5 [arm64] Use B instruction key for return address signing
The C++ code uses the A instruction key for return address signing,
which is the default for Clang and GCC when the -mbranch-protection
option is used (although this can be configured to use the B key).

Using the B key for JS means that it's not possible to use an A key
signing gadget to replace a return address signed with the B key and
vice-versa. This should offer a degree of separation from the C++ side.

Also add first uses of these flags in pipeline.cc by skipping certain

8ee54c92c7 [wasm] Do not log code of functions whose module is not fully loaded
This is a reland of change Idb1061cafcba7a2a654a207402dca520f79a3bbe.
The access to wire_bytes has been protected by using atomic operations.

Under some circumstances, Wasm is trying to log code for which the
wire bytes are not fully loaded yet. This can happen during streaming
compilation when a few functions are already fully compiled but the
engine is still streaming the remaining functions.

If the profiler now kicks in, it will attempt to log these freshly
compiled functions. As these functions will not be executed before
the module is fully compiled, we can simply defer the logging in this
case.

This was reverted because of a test timing out on slow_path

the test is just really slow, and was skipped on this variant
in https://crrev.com/c/2237628. Relanding without changes.

f6874c73bd [globals] Change uc32 to be unsigned
Prior to this change, uc16 was typedef'd to (unsigned) uint16_t while
uc32 was typedef'd to (signed) int32_t.

For consistency, and to avoid unexpected behavior around
signed/unsigned comparisons, this changes uc32 to the unsigned
uint32_t type.

As part of this change, old-style error passing (return -1, check for
negative return values) was updated to use named error values.

d8c9ae5295 [compiler] Fix double error reporting for parser errors
Remove error reporting from parsing::Parse*, since in most cases we
didn't actually want them (clear errors afterward), and there was an
issue where Compiler::Compile would try to report errors already
reported in ParseAny, which ended up triggering unreachable code.

As a drive-by, move some one-off parse exception handling in
test-parsing into a CHECKED_PARSE_PROGRAM macro which replaces all the
"necessarily positive" calls to parsing::ParseProgram.

c64c060b12 [wasm] Remove WasmDebugInfo and InterpreterHandle
The interpreter is only used for testing, and is now instantiated and
invoked directly instead of via the {WasmDebugInfo}, holding the
{InterpreterHandle}.

This CL removes both classes.

ba688c6ec9 [wasm] Rename anyref to externref, anyref flag/feature to reftypes
The reference types wasm proposal dropped all subtyping. Subsequently,
the 'anyref' type was renamed to externref.
This changes all references of the *type* anyref to externref.
Additionally, the flag that permits this extension is renamed to
"reftypes" to mirror the proposal name.

7637ed59c9 [wasm][debug] Fully tier up on Debugger.disable
When the last debugger is disabled, we tier up the module to TurboFan.
Doing this in the background creates problems with profiling, where the
debugger is disabled before starting to profile, in order to guarantee
profiling of top-tier code.

Hence this CL changes the logic such that we only return from the
{TierUpAllModulesPerIsolate} methods once tier up is complete. Since
the DevTools frontend disables all debuggers before starting a profile,
this will ensure that all new calls execute TurboFan code.
Because of this change, the {TriggerRecompilation} method is renamed to
{RecompileForTiering}.

The test cases stay unchanged (do a busy wait until tier up is done),
because in the multi-isolates tests it is not guaranteed that tier up is
complete after disabling a single debugger.

47e501e169 [wasm][interpreter] Remove threads support
The wasm interpreter was always single-threaded, and there are no plans
to change this. Still, there was a concept of threads, but with the
hard-coded constraint that there is always exactly one of them.

In order to clean up the code, and as a preparation to remove more
unneeded functionality before moving the interpreter over to the test
directory, this CL removes the concept of threads and merges the
{ThreadImpl} class into {WasmInterpreterInternals}.

Drive-by: Remove the dead {GetFrameCount} method.

63e243a0c2 [wasm] Do not log code of functions whose module is not fully loaded
Under some circumstances, Wasm is trying to log code for which the
wire bytes are not fully loaded yet. This can happen during streaming
compilation when a few functions are already fully compiled but the
engine is still streaming the remaining functions.

If the profiler now kicks in, it will attempt to log these freshly
compiled functions. As these functions will not be executed before
the module is fully compiled, we can simply defer the logging in this
case.

1495b3db39 Reland "[wasm-simd][liftoff] Fix I64x2Mul"
This relands commit 76debfda32.

This fix here is to convert the original mjsunit test into a
cctest, where we check for SIMD support, and skip the test.
We don't have lowering for I64x2 yet, so this is the
workaround.

Original change's description:
> [wasm-simd][liftoff] Fix I64x2Mul
>
> The I64x2Mul overwrote the lhs/rhs if they are the same as dst. So when
> deciding if we need temporaries, we should not only check the
> cache_state, but whether they alias dst or not.
