This patch begins adding support for lowering to the XOP VPERMIL2PD/VPERMIL2PS shuffle instructions - adding the X86ISD::VPERMIL2 opcode and cleaning up the usage.
The internal llvm intrinsics were assuming the shuffle mask operand was the same type as the float/double input operands (I guess to simplify the intrinsic definitions in X86InstrXOP.td to a single value type). These needed changing to integer types (matching the clang builtin and the AMD intrinsics definitions), an auto upgrade path is added to convert old calls.
Mask decoding/target shuffle support will be added in future patches.

This patch adds the complete AMD Bulldozer XOP instruction set to the memory folding pattern tables for stack folding, etc.
Note: Many of the XOP instructions have multiple table entries as it can fold loads from different sources.
