[avx] Add patterns for combining vextractf128 + vmovaps/vmovups/vmobdqu to
vextractf128 with 128-bit mem dest. Combines vextractf128 $0, %ymm0, %xmm0 vmovaps %xmm0, (%rdi) to vextractf128 $0, %ymm0, (%rdi) rdar://11082570 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153139 91177308-0d34-0410-b5e6-96231b3b80d8
