Changes in directory llvm/lib/Target/X86:
X86InstrSSE.td updated: 1.45 -> 1.46
---
Log message:
Change SSE pack operation definitions to fit what the intrinsics expected.
For example, packsswb actually creates a v16i8 from a pair of v8i16. But since
the intrinsic specification forces the output type to match the operands.
