Fix VINSERTF128/VEXTRACTF128 to be marked as FP instructions. Allow execution dependency fix pass to convert them to their integer equivalents when AVX2 is enabled.

Remove X86-dependent stuff from SSEDomainFix.
...
This also enables domain swizzling for AVX code which required a few
trivial test changes.
The pass will be moved to lib/CodeGen shortly.

Fix a nasty bug where a v4i64 was being wrong emitted with 32-bit
...
permutations. Also tidy up some patterns and make them close to their
instruction definition!

Add support for breaking 256-bit v16i16 and v32i8 VSETCC into two 128-bit ones, avoiding sclarization. Add vex form of pcmpeqq and pcmpgtq. Fixes more cases for PR10712.

Now that we have a canonical way to handle 256-bit splats:
...
vinsertf128 $1 + vpermilps $0, remove the old code that used to first
do the splat in a 128-bit vector and then insert it into a larger one.
This is better because the handling code gets simpler and also makes a
better room for the upcoming vbroadcast!

Splats for v8i32/v8f32 can be handled by VPERMILPSY. This was causing

infinite recursive calls in legalize. Fix PR10562

Use the splat index to generate the desired shuffle. Otherwise we
...
could only get undefs and the vector shuffle becomes an undef,
generating wrong code.
