 // Random ideas for the X86 backend: SSE-specific stuff.

-- Consider eliminating the unaligned SSE load intrinsics, replacing them with
-  unaligned LLVM load instructions.

+SSE Variable shift can be custom lowered to something like this, which uses a
+small table + unaligned load + shuffle instead of going through memory.
