The main problem here is that the macro-assembler for Pmaddubsw and
Pmaddwd expects dst == src1 when AVX is not supported.

For Pmaddwd, we use an existing macro to define the function.

For Pmaddubsw, we do the AVX check inline and use movaps if not
supported because it requires a SSSE3 scope, and we don't have an
existing macro to do this (we can find other uses and clean up as
necessary in the future).

v8_libsampler was previously split off to serve goals that were never
achieved and seem unlikely to be. Since the division creates a
dependency cycle between v8_base_without_compiler and v8_libsampler
(where one edge is a #include that breaks gn check), this moves
sampler.* back into v8_base_without_compiler and removes the
v8_libsampler target.

Split out all the headers from v8_compiler/v8_compiler_opt and
v8_base_without_compiler into v8_internal_headers since the headers
have inter-dependencies that otherwise make it impossible to satisfy gn
check.

Also adds new v8_header_set torque_runtime_support that exports
src/torque/runtime-support.h separately from the generated headers.

This reduces the number of gn check failures from 169 to 59.

This CL removes the includes of src/wasm files from the API if Wasm is
disabled (v8_enable_webassembly=false). This will allow to later
remove the whole src/wasm directory from compilation.
Since we do not want to modify the exposed API in a no-wasm build, we
instead make all Wasm-related functions fail.

For adding stack checks in optimized code, we compute a conservative
estimate of the frame size in the case of a deoptimization. Earlier we
included the size of arguments adaptor frames used when actual arguments
didn't match formal parameter count. Though we don't have an explicit
adaptor frame, we should still include the size of these additional
arguments when computing the frame size.

Calls >4gb may have pretty bad performance on 64bit processors that use
32bits to encode branch prediction. By passing in a function in the
binary as a hint to mmap it's more likely we'll be given an address
close to the binary. This may significantly improve performance on many
types of 64bit cores, especially those without hyperthreading.

To improve performance of parking, keep the thread state in an atomic
variable instead of protecting it with a mutex.

However the mutex was used e.g. to force Unpark() to block while the
safepoint operation was still running. Therefore the safepoint algorithm
has to change as well.

Park() and Unpark() use CAS operation to transition the state.
Safepoint() uses a relaxed load for checking whether a safepoint was
requested. Since Safepoint(), Park() and Unpark() all have a slow path,
there is no need for busy-waiting on the main thread.

We need two more ThreadStates:
* SafepointRequested: This state is set by GlobalSafepoint to force
    Running threads into the slow path on Safepoint() and Park(). This
    state also replaces the separate atomic<bool> safepoint_requested_
    field we used before.
* ParkedSafepoint: This state is set by GlobalSafepoint as well to force
    parked threads into the slow path on Unpark().

When stopping all threads, GlobalSafepoint transitions states from
Running --> SafepointRequested and Parked --> ParkedSafepoint to force
the slow path for all three methods. After performing the transition
for each thread we know the exact number of Running threads and wait
until each of them either reached a safepoint or parked itself.

we can use the SSE version of the same code sequence. However, there is
a potentially better lowering that only requires SSE2, which has less
instructions, but will only work better if we have rip-relative
constants (otherwise even using ExternalReference it would be 2 moves).

Instead of moving the stand-alone logic to the base heap, allows
specific heaps to override their stand-alone GC behavior. This allows
CppHeap to reuse the unified heap bottlenecks and visitors for
testing. This works as long as any v8 references are empty as there is
no Isolate attached to the heap in this case.

Port 52cc7ba9

Original Commit Message:

    This renames more fields holding "ValueKind" or methods operating on
    "ValueKind" to contain "kind" instead of "type".
    It also renames "is_reference_type" to "is_reference" on both ValueType
    and ValueKind, as the "_type" prefix is kind of implicit from the
    argument.

Using an out-parameter for the SFI data type in
GetSharedFunctionInfoCode() avoids loading the CodeKind in
CompileLazy().

We experimentally globally enable loop unrolling for wasm code. This
might be reverted based on the results of perf bots.

Additional change: Add LoopExitValue to Int64Lowering, plus a small
simplification.
