0363eb4da0 [wasm][debug] Generate sidetables for stepping lazily
We are often stepping multiple times without inspecting the state
in-between. Hence, the generated debug side table is often not being
used. Instead of always generating it, we can generate it lazily on
demand, which can avoid the need to generate it at all.

Conditional breakpoints are not implemented yet; the condition is just
ignored for wasm. This CL adds a test for conditional breakpoints. The
output is expected to change once the implementation is finished.

44fa34084a [wasm-gc] Fixes around rtts, especially functions
Changes:
- Rename ObjectReferenceKnowledgs::object_must_be_data_ref to
  reference_kind, introduce an enum to describe it.
- In both compilers, remove the dynamic check whether the object is an
  array/struct. This is known statically. Instead, if we are checking
  for a function, just check for rtt equality and exit.
- Remove is_data_ref_type(), replace it in the compilers with calls to
  has_signature().
- Restructure AllocateSubRtt() to handle function rtts properly.
- Add a couple execution tests.

2. --turbo-nci-cache-ageing
3. --turbo-nci-delayed-codegen

Flag 1. was used by a testing mode that is no longer used. Flags 2. and
3. were used to experiment with codegen and cacheing heuristics, no
longer needed now that work is suspended.

df98901c19 [interpreter] Store accumulator to callee after optional chain checks
Optional chain checks check if the object is null or undefined and
if it is we don't perform the load but just load accumulator with
undefined. For calls the value of the accumulator needs to be stored
in the callee register. We were doing this only when the object
isn't null or undefined. This cl fixes it by storing it to callee
always.

dae07e7a34 [modules][api] Remove import assertions sorting for HostImportModuleDynamically callback
Hosts are not supposed to rely on the ordering of import assertions list
received from V8. Thus, as a simplification, remove the sorting of the
import assertions passed to the HostImportModuleDynamically callback.

Update the corresponding test so that it doesn't require any particular
ordering of assertions.

Import asssertions for static imports will continue to be sorted. These
need to have a consistent ordering for purposes of deduplication in
SourceTextModuleDescriptor::module_requests_, so removing sorting of
these wouldn't simplify much.

e6e9721b55 cppgc: Increase tolerance in MetricRecorder unittests
Tolerance was set to 50 microseconds. This is not enough and causes
flaky failures. Tolerance is needed because we record milliseconds and
an empty scope can still take a few milliseconds to create and destroy.

Increasing the tolerance to 500 microseconds should suffice and makes
sense for the test. All expected values are in 10s of milliseconds, so
half a millisecond tolerance should be reasonable.

31d2bb8670 Reland2 [super] Store home object in Context instead of JSFunction
Fix 1: Track Scope::needs_home_object and Scope::uses_super_property
accurately. When "eval" is seen, figure out whether it can access
"super" and if yes, set the corresponding home object as needed.

Fix 2: The object literal scope shouldn't be entered for things
inside spreads.

Original: https://chromium-review.googlesource.com/c/v8/v8/+/2563275
Previous reland: https://chromium-review.googlesource.com/c/v8/v8/+/2637220

This saves memory (the home object doesn't need to be stored for each
method, but only once per class) and hopefully makes the home object
a constant in the optimized code.

12f8ac4713 Revert "Reland [super] Store home object in Context instead of JSFunction"
This reverts commit f6450b97ec.

Reason for revert: ClusterFuzz bugs

Original change's description:
> Reland [super] Store home object in Context instead of JSFunction
>
> 1) Computed property keys (esp functions in them) shouldn't be inside
> the object literal scope.
>
> 2) I was using an imprecise "maybe uses super" and storing it to
> preparse data. This won't fly, since it pollutes sister scopes and
> leads to confusion wrt whether an object literal needs a home object
> or not. Made it precise (mostly cancelling changes in the original CL).
>
> 3) PreParser::NewSuperPropertyReference was creating a VariableProxy for
> this_function (which made it used) -> inconsistent scopes between
> parsing and preparsing.
>
> 4) MultipleEntryBlockContextScope was messing up the accumulator
>
> Original: https://chromium-review.googlesource.com/c/v8/v8/+/2563275

> This saves memory (the home object doesn't need to be stored for each
> method, but only once per class) and hopefully makes the home object
> a constant in the optimized code.

9c120b753d [wasm-simd][x64] Fix encoding of vcvtdq2pd
vcvtdq2pd was incorrectly declared to take 3 operands, the use of the
macro Cvtdq2pd meant that the call was vcvtdq2pd(dst, dst, src). This
is an incorrect encoding. Our tests happen to pass because dst was xmm0,
which made it accidentally correct.

This fixes it by moving cvtdq2pd out of the macro list.

591db5d98b [wasm] Fix data race in lazy compilation
Instead of updating the detected features set directly, use the
synchronized {OnCompilationStopped} method.
In order to avoid this error in the future, the whole
{detected_features()} getter is removed, as it returns a pointer which
can only be accessed when holding the mutex anyway. Also, the refactored
code was the only user of this dangerous method.

Drive-by: Pass the WasmFeatures set by value, since it's just an
EnumSet.
Drive-by 2: Remove a print line from the regression test which can be
confusing if the test is picked up again by foozzie.
