3157ef1c13 This is the first step towards refactoring the x86 vector shuffle code. The
general idea here is to have a group of x86 target specific nodes which are
going to be selected during lowering and then directly matched in isel.

The commit includes the addition of those specific nodes and a *bunch* of
patterns, and incrementally we're going to switch between them and what we
have right now. Both the patterns and target specific nodes can change as
we move forward with this work.

642eb02045 - Teach SSEDomainFix to switch between different levels of AVX instructions. Here we guess that AVX will have domain issues, so just implement them for consistency and in the future we remove if it's unnecessary.
- Make foldMemoryOperandImpl aware of 256-bit zero vectors folding and support the 128-bit counterparts of AVX too.
- Make sure MOV[AU]PS instructions are only selected when SSE1 is enabled, and duplicate the patterns to match AVX.
- Add a testcase for a simple 128-bit zero vector creation.

8c05a850f4 Begin to support some vector operations for AVX 256-bit intructions. The long
term goal here is to be able to match enough of vector_shuffle and build_vector
so all avx intrinsics which aren't mapped to their own built-ins but to
shufflevector calls can be codegen'd. This is the first (baby) step, support
building zeroed vectors.

d29583bd32 Fix <rdar://problem/8282498> even if it doesn't reproduce on trunk.
When a register is defined by a partial load:

  %reg1234:sub_32 = MOV32mr <fi#-1>; GR64:%reg1234

That load cannot be folded into an instruction using the full 64-bit register.
It would become a 64-bit load.

This is related to the recent change to have isLoadFromStackSlot return false on
a sub-register load.

045573ce21 Add AVX matching patterns to Packed Bit Test intrinsics.
Apply the same approach of SSE4.1 ptest intrinsics but
create a new x86 node "testp" since AVX introduces
vtest{ps}{pd} instructions which set ZF and CF depending
on sign bit AND and ANDN of packed floating-point sources.

This is slightly different from what the "ptest" does.
Tests comming with the other 256 intrinsics tests.
