x86: Fix aliasing issues with SIMD instructions

[Sleigh-InSPECtor]

Several of the SIMD instructions have incorrect semantics when both the source and destination register are the same. Essentially, parts of the source register are modified via writes to the destination register while they are still needed.

This PR fixes the following:
