[PPC] Prefer direct move on power8 if load 1 or 2 bytes to VSR Power8 has MTVSRWZ but no LXSIBZX/LXSIHZX, so move 1 or 2 bytes to VSR through MTVSRWZ is much faster than store the extended value into stack and load it with LXSIWZX. This patch fixes pr31144. Differential Revision: https://reviews.llvm.org/D27287 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@289473 91177308-0d34-0410-b5e6-96231b3b80d8
