This is similar to what is already done in x64, define a macro list for
all the *sd instructions (prefix f2 0f), and use this macro list to

By delegating to the macro-assembler, emit AVX instructions for some
float opcodes (float sqrt, round, conversions to and from int,
extract/insert/load word).

Since they now support AVX, we rename the instruction ops to remove the
SSE prefix, changing it to be IA32.

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.

There are instructions that take 7 bytes, e.g.

Hence increase the padding from 12 characters to 14 characters to
restore alignment.

Drive-by: Rewrite the padding loop to make it more readable and add a

This is a reland of a16add80.

The fixes are adding disassembly for pcmpgtq and vpcmpgtq.
While fixing also noticed a mistake in assembler for pcmpgtq,
which flipped dst and src.
Also realized that we don't detect SSE4.2, so adding that in.

PS2 contains these changes.

- i32x4.trunc_sat_f64x2_s_zero
- i32x4.trunc_sat_f64x2_u_zero
- f32x4.demote_f64x2_zero
- f64x2.promote_low_f32x4

The code sequences are exactly the same as on x64.

Needed to add some more instructions, and we don't have macro lists for
these instructions yet, so individually define them for now. We can
factor them into lists in a future change.

We can have more optimizations for this instruction, they leave some
junk in the top lanes of dst, but that doesn't matter:

- when lane is 1: we use movshdup, this is 4 bytes long
- when lane is 2: use movhlps, this is 3 bytes long
- otherwise use shufps (4 bytes) or pshufd (5 bytes)

All of which are better than insertps (6 bytes).

This is pretty similar to x64 version, except that there is no signal

dst might not be the same as src0 (since we don't define them to be
equals in the instruction-selector if AVX is enabled), so the minps
and maxps comparisons were incorrect.

I found this while trying to run some spec tests, so not adding any
unittest, eventually when the spec tests are enabled, this will be
covered.

For SIMD instructions that use aligned moves (like movaps or movapd), we
don't have correct memory alignment for SIMD moves yet. Switch to to
movupd.
