Protect PPC Altivec patterns with a predicate
In preparation for the addition of other SIMD ISA extensions (such as QPX) we need to make sure that all Altivec patterns are properly predicated on having Altivec support. No functionality change intended (one test case needed to be updated b/c it assumed that Altivec intrinsics would be supported without enabling Altivec support). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177152 91177308-0d34-0410-b5e6-96231b3b80d8
