palignr has a false dependency, so use punpckhbw. Plus optimize for AVX,
which can have 1 less instruction.

The logic for i16x8.extmul_high_u is slightly complicated (SSE case)
to handle register aliasing. This allows us to have the most flexible
register allocation, and be able to optimize the most

One of the x86 ISA extensions is confusingly named SSSE3 (*Supplemental*

by SSE4.

This CL adds testing coverage for x86 CPUs that support SSE3
instructions, but do not support SSSE3 instructions. Chrome supports
these CPUs, and they are used by a non-trivial amount of Chrome's users
on Windows.

Torque generally supports marking things as unused by adding a single
underscore to the front of identifiers. For locals, this feature works
fine. For macros, it's only half-implemented: attempting to look up a
macro that starts with _ fails (as it should), but the compiler also
complains if the macro is unused. This change avoids emitting the latter
error.

This changes the behavior of SetBreakpointForScript to find more
accurate break positions.

Previously, setting a breakpoint would only consider the shared
function info that contained the requested position for setting a
breakpoint. More intuitively, a breakpoint should not necessarily
be set in a function that contains the position, but in the closest
breakable location that comes after the position we requested.

To achieve this we:
1. find the shared function info of the inner most function
that contains the requested_position.
This function's end position is used to find other shared function
infos in step 2.

2. search for all shared function infos that intersect with the
range [requested_position, inner_most_function.break_position[.

3. From the shared function infos extracted in 2, find the one
that has the closest breakable location to requested_position.

Port 8d0f5a04

Original Commit Message:

    Due to a recent change Liftoff used different register configurations
    in the pointer-compression and no-pointer-compression setups. This
    caused a mismatch between the registers used by Liftoff and the
    registers spilled by the WasmDebugBreak builtin.

    With this CL the same register configuration is used both with and
    without pointer compression. Even without x28 there are 24 registers
    that can be used. Moreover, 24 registers can be spilled without
    padding, which would be needed with 25 registers to preserve stack
    alignment.

    Drive-by change: Use Reglist in frame-constants on all platforms.
