df4b35e3dd 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.

d8b7dd5252 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!

a534780da0 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.

666f500592 Update test to not use the scalar type to splat from a load

fc0a702128 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!

5f1d8abf75 Splats for v8i32/v8f32 can be handled by VPERMILPSY. This was causing
infinite recursive calls in legalize. Fix PR10562

a5134a0ea3 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.
