[PowerPC] Match vec_revb builtins to P9 instructions. Power9 has instructions that will reverse the bytes within an element for all sizes (half-word, word, double-word and quad-word). These can be used for the vec_revb builtins in altivec.h. However, we implement these to match vector shuffle nodes as that will cover both the builtins and vector shuffles that occur in the SDAG through other means.
