[PPC] Adjust some PowerPC tests to account for presence/absence of VSX 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

Enable unaligned memory access on PPC for scalar types Unaligned access is supported on PPC for non-vector types, and is generally more efficient than manually expanding the loads and stores. A few of the existing test cases were using expanded unaligned loads and stores to test other features (like load/store with update), and for these test cases, unaligned access remains disabled. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177160 91177308-0d34-0410-b5e6-96231b3b80d8
