1. rename the movhp patfrag to movlhps, since thats what it actually matches 2. eliminate the bogus movhps load and store patterns, they were incorrect. The load transforms are already handled (correctly) by shufps/unpack. 3. revert a recent test change to its correct form. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@86415 91177308-0d34-0410-b5e6-96231b3b80d8
