[X86] Remove FsVMOVAPSrm/FsVMOVAPDrm/FsMOVAPSrm/FsMOVAPDrm. Due to their placement in the td file they had lower precedence than (V)MOVSS/SD and could almost never be selected.

The only way to select them was in AVX512 mode because EVEX VMOVSS/SD was below them and the patterns weren't qualified properly for AVX only. So if you happened to have an aligned FR32/FR64 load in AVX512 you could get a VEX encoded VMOVAPS/VMOVAPD.

I tried to search back through history and it seems like these instructions were probably unselectable for at least 5 years, at least to the time the VEX versions were added. But I can't prove they ever were.
