Patch by Bill Seurer; committed on his behalf. These test cases generate slightly different code sequences when VSX is activated and thus fail. The update turns off VSX explicitly for the existing checks and then adds a second set of checks for most of them that test the VSX instruction output. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@220019 91177308-0d34-0410-b5e6-96231b3b80d8
