Simon Pilgrim e85506b6e0 [X86][XOP] Support for VPERMIL2PD/VPERMIL2PS 2-input shuffle instructions 
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.

Simon Pilgrim 9602d678cb [X86][SSE] (Reapplied) Replace (V)PMOVSX and (V)PMOVZX integer extension intrinsics with generic IR (llvm) 
This patch removes the llvm intrinsics VPMOVSX and (V)PMOVZX sign/zero extension intrinsics and auto-upgrades to SEXT/ZEXT calls instead. We already did this for SSE41 PMOVSX sometime ago so much of that implementation can be reused.
