[PATCH] D18189: [X86][XOP] Support for VPPERM byte shuffle instruction

Reduced the patch to just the plumbing for the X86ISD::VPPERM opcode.

Yeah, VPPERM is pretty nifty - I'll probably try to make use of at least some of its features (bitreverse comes to mind) in future patches, but for now I'm just interested in binary shuffle combining.
