The optimal implementation is in TurboFan x64 codegen, move it into
shared-macro-assembler, and have TurboFan ia32 and Liftoff use it. The
optimal implementation accounts for AVX2 support.

We add a couple of AVX2 instruction to ia32 in sse-instr.h, not all of
them are used, but follow-up patches will use them, so we add support
(including diassembly and test) in this change.

Drive-by clean up to test-disasm-x64.cc to merge 2 AVX2 test sections.

TurboFan currently calls into runtime for these two instructions, but
there is a better 4-instruction lowering that Liftoff already uses. Move
this into macro-assembler so we can share this across both compilers. We
name this PopcntHelper because there isn't a Cnt on ARM64 that works on
Word32/Word64.

Use logical shifts to emulate arithmetic shift, by first adding a bias
to make all signed values unsigned, then subtracting the shifted bias.
Details are in code comments for SharedTurboAssembler::I64x2ShrS.

Also refactor ia32 (which was already using this algorithm) to use the
shared macro-assembler function. And convert Liftoff's implementation as
well.

The number of arguments for the LiftoffCompiler has grown significantly
since its initial implementation, and it becomes hard to keep track of
all options at the call sites.

This CL refactors all optional parameters into a {LiftoffOptions} struct
which has a factory-like interface.
This will allow us to add more options in the future, e.g. for dynamic
tiering.
