Add support for OSR to baseline code.
We compile baseline and perform OSR immediately when the bytecode budget
interrupt hits.

Drive-by: Clean-up deoptimizer special handling of JumpLoop by using
the newly introduced GetBaselinePCForNextExecutedBytecode instead of
GetBaselineEndPCForBytecodeOffset.

The x64 and ia32 implementations are the same, modulo function
signature. x64 has a kScratchDoubleReg available, ia32 takes it as a
argument. We standardize on the ia32 function signature and have callers
on x64 pass in the scratch register.

Move many test helpers into wasm-simd-utils. These helper functions can
potentially be useful for relaxed-simd test in the future. I left behind
simd specific test helpers, like load extend helpers, because those are

JSFunctions can store a pointer to baseline code, which would trigger
that code to be serialized in the context serializer. Since we don't
support baseline code serialization, we have to flush these baseline

The implementation of Flatten() Torque generates for CSA struct types
and the current implementation of EmitCCValue make heavy use of
std::make_tuple and std::tuple_cat, which had a noticeable impact on
build times of generated files including these outputs.
This CL eliminates all uses of std::tuple_cat and most uses of
std::make_tuple.

SharedTurboAssembler is shared between ia32 and x64. It contains shared
functionality between these two backends. It derives from
TurboAssemblerBase, and the backend-specific TurboAssembler derives from
SharedTurboAssembler. That way, LiftoffAssembler does not need to
change.

As an example, we move a single member function I64x2SConvertI32x4High
into SharedTurboAssembler. This function has the exact same
implementation on ia32 and x64, and is now defined in a single place.

... when they are enabled via the GN flag.

Also disable this optimizaion for CFI builds for now.

Sheriffs: This CL adds ~1.2-1.4Mb of memory overhead per Isolate on
certain configurations and that's expected. This is a temporary fix
until the full solution is implemented.
See the design doc linked to the issue for details.

This test is unnecessarily slow due to the CSA test suite for
SwissNameDictionary doing excessive runtime calls at the moment. This
causes timeouts on various bot configurations.

This is the second reland of
https://chromium-review.googlesource.com/c/v8/v8/+/2744138. It
shortens the runtime of further tests.

Original description:


This CL is part of a series that adds the C++ implementation of
SwissNameDictionary, a deterministic property backing store based on
Swiss Tables.

This CL adds the actual tests for SwissNameDictionary, defined in
test-swiss-name-dictionary-shared-tests.h, using the infrastructure
in test-swiss-name-dictionary-infra.[h|cc].
