This patch corresponds to review: https://reviews.llvm.org/D19825 The new lxvx/stxvx instructions do not require the swaps to line the elements up correctly. In order to select them over the lxvd2x/lxvw4x instructions which require swaps, the patterns for the old instruction have a predicate that ensures they won't be selected on Power9 and newer CPUs. llvm-svn: 282143
