074cfd613b [wasm-gc] Classification functions
The latest wasm-gc spec introduces classification functions
{ref.as, ref.is, br_on}_{func, data, i31}, to cast values typed as
anyref and eqref.

ce6b373de8 [wasm-gc] Disallow type checks from eqref and anyref
As per the latest wasm-gc spec, type checks are only allowed from
subtypes of dataref and funcref. To cast from a more general type,
specialized classification instructions need to be used (will come
later).

e0644bbbce [wasm-gc] Implement dataref

The heap type expected for arrays and structs when interacting with JS
changes from eq to data.

- i32x4.trunc_sat_f64x2_s_zero
- i32x4.trunc_sat_f64x2_u_zero
- f32x4.demote_f64x2_zero
- f64x2.promote_low_f32x4

Drive-by fix:

- f64x2.promote_low_f32x4 accesses out of bounds for the global, the
result only has 2 doubles
- fcvtn in simulator needs to clear top bits of the Q reg

f111e0c572 [wasm-simd] Fix byte order when setting mask values
Multi byte values get stored on native host order when
arrays are being constructed, however as Wasm is LE enforced,
they get reversed on BE machines during simd load. This causes
incorrect values loaded into vector registers.

This CL will force mask elements to be saved in byte sizes
to eliminate endianness issues.

c5c5d1447f [wasm] Fix tier down on streaming with error
Recompilation for tier down should not be triggered if the module had a
compile error. This CL ensures that by moving the recompilation a bit
later in the async compilation, to a place where a compile error would
have been detected already. An added DCHECK would catch similar bugs
earlier (crashing instead of timing out).

bce455a3f0 [wasm][serialization] Skip redundant information
Writing out the number of functions in the module is unnecessary. That
number is only used for validation when reading back the value, but only
validating that number is pretty arbitrary and does not protect against
bugs or attacks. Hence skip these two header fields.

- In function-body-decoder-impl.h, update rtt.canon to always produce

- Pass a unit32_t type index over a HeapType to all rtt-related

- Remove infrastructure for abstract-type rtts from the wasm compilers,

- Remove ObjectReferenceKnowledge::rtt_is_i31. Remove related branches
  from ref.test, ref.cast and br_on_cast implementations in the wasm
  compilers.
- Remove unused 'parent' field from WasmTypeInfo.
- Make the parent argument optional in NewWasmTypeInfo, CreateStructMap,

- Use more convenient arguments in IsHeapSubtypeOf.
- Update tests.

39645430e2 [inspector][wasm] Remove obsolete Debugger.executeWasmEvaluator().
With https://crrev.com/c/2087396 we introduced a new CDP method
`Debugger.executeWasmEvaluator()`, which we originally intended
to use as the foundation for Debug-Evaluate on Wasm frames.

However in the process of prototyping we learned that it is too
costly and too inefficient to use WebAssembly modules here, and
we switched to regular Debug-Evaluate with JavaScript instead
(with a special debug proxy exposed that allows JavaScript to
peak into the Wasm frame), since JavaScript is better suited
for short-lived / short-running snippets and we don't need
clang and wasm-ld then to generate these snippets.

The JavaScript exposed debug proxy (as described in [1]) not
only enables more powerful and flexible Debug-Evaluate for the
DWARF C/C++ extension, but also serves as the basis for various
aspects of the Basic Wasm Developer Experience.

In order to pay down technical debt and to keep the maintenance
overhead low, we should remove the initial prototype now, also
to ensure that we don't accidentally attract other users of CDP
to rely on this unsupported API (despite it being marked as
"experimental").

3bb0f51aa5 [wasm-simd][x64] Pattern match on shufps-style shuffles
When a 8x16 shuffle matches a 32x4 shuffle (every group of 4 indices are
consecutive), and the first 2 indices are in the range [0-3], and the
other 2 indices are in the range [4-7], then we can match it to a
shufps. E.g. [0,2,4,6], [1,3,5,7]. These shuffles are commonly used to
extract odd/even floats.

This moves some fields and methods from the WasmRunner template to the
WasmRunnerBase base class. This avoids repeated compilation for the
different instantiations of the WasmRunner template.

Additional changes:
- SetUpTrapCallback, SetThreadInWasmFlag, and ClearThreadInWasmFlag are
  static now.
- CheckUsedExecutionTier is unused, and did not even compile any more.
  In the template class this was OK, because it's only compiled on first

f368298445 [wasm] Initialize compile job early
Since the compile job can always be reused after creation (even if it
runs out of work), we do not need the logic to (re-)initialize it. In
fact, it will always only be initialized once already.
This allows us to initialize it once during construction of the
compilation state (or right after the initialization), and then access
it without locks later.

In addition, this CL
1) renames "current_compile_job_" to "compile_job_", since there will
   always only be one now;
2) removes the {ScheduleCompileJobForNewUnits} method, and just does a
   {compile_job_->NotifyConcurrencyIncrease()} instead;
3) removes the {has_priority_} field and just directly does a
   {compile_job_->UpdatePriority} call.

The streaming test platform needed to be fixed to avoid calling {Join}
on the job handle, which would invalidate the handle afterwards.
Instead, we just run all tasks as long as there are any.

7c98abdb78 [x64][wasm-simd] Pattern match 32x4 rotate
Code like:

  x = wasm_v32x4_shuffle(x, x, 1, 2, 3, 0);

is currently matched by S8x16Concat, which lowers to two instructions:

  movapd xmm_dst, xmm_src
  palignr xmm_dst, xmm_src, 0x4

There is a special case after a S8x16Concat is matched:.

- is_swizzle, the inputs are the same
- it is a 32x4 shuffle (offset % 4 == 0)

Which can have a better codegen:

- (dst == src) shufps dst, src, 0b00111001
- (dst != src) pshufd dst, src, 0b00111001

Add a new simd shuffle matcher which will match 32x4 rotate, and
construct the appropriate indices referring to the 32x4 elements.

pshufd for the given example. However, this matching happens after
S8x16Concat, so we get the palignr first. We could move the pattern
matching cases around, but it will lead to some cases where
where it would have matched a S8x16Concat, but now matches a
S32x4shuffle instead, leading to worse codegen.

Note: we also pattern match on 32x4Swizzle, which correctly generates

c8166827b5 [wasm][profiler] Report source URL and position
So far we reported the script ID, but DevTools ignores that and uses the
source url instead. That url was just set to "wasm ", which the frontend
couldn't make any sense of.
This CL fixes this by passing the source URL to the code create event,
and also setting the position of the code inside the script (i.e.
wasm module).

aee852292d [wasm-simd][x64] Prototype extended pairwise addition
Add new macro-assembler instructions that can handle both AVX and SSE.
In the SSE case it checks that dst == src1. (This is different from that
the AvxHelper does, which passes dst as the first operand to AVX
instructions.)

Sorted SSSE3_INSTRUCTION_LIST by instruction code.

Header additions are added by clangd, we were already using something
from those headers via transitive includes, adding them explicitly gets
us closer to IWYU.

Codegen sequences are from https://github.com/WebAssembly/simd/pull/380
and also

Add new instruction vpaddl for signed and unsigned integers, adding
assembler, disassembler, simulator support, and also tests.

The signed and unsigned opcodes for vpaddl are separate enums, because
the helper EncodeNeonUnaryOp only takes a NeonSize (not NeonDataType). I
considered changing the signature, but none of the other instructions
use a NeonDataType, so it seems unnecessary.

Lood/Stores need to be reversed manually on BE machines and as such
LoadLane and StoreLane opcodes cannot be done in a single instruction.
Therefore we divide them into separate "Load/Store" and "operation"
nodes.

Issue 1: WasmEngine UAF when CompilationState is destroyed
asynchronously
Fix: Include https://chromium-review.googlesource.com/c/v8/v8/+/2565508

Issue 2: In gin, JobTask lifetime is not extended beyond
JobHandle, thus making CancelAndDetach unusable.

> Fix: Manually calling NewDefaultJobHandle and passing the MockPlatform

> Additional change:
> - CancelAndDetach is now called in ~CompilationStateImpl() to make sure
> it's called in sequence with ScheduleCompileJobForNewUnits

> Original CL description:
> To avoid keeping around a list of job handles, CancelAndDetach() is
