Merge vector stores into wider vector stores (PR21711)
This patch resolves part of PR21711 ( http://llvm.org/bugs/show_bug.cgi?id=21711 ).
The 'f3' test case in that report presents a situation where we have two 128-bit
stores extracted from a 256-bit source vector.
Instead of producing this:
vmovaps %xmm0, (%rdi)
vextractf128 $1, %ymm0, 16(%rdi)
This patch merges the 128-bit stores into a single 256-bit store:
vmovups %ymm0, (%rdi)
