Intuitively, the memory folding pair should have the same mnemonic.

This patch removes

  {X86::SENDUIPI,X86::VMXON}

in the auto-generated table.

  {X86::MOVLHPSrr,X86::MOVHPSrm}
  {X86::VMOVLHPSZrr,X86::VMOVHPSZ128rm}
  {X86::VMOVLHPSrr,X86::VMOVHPSrm}

It seems the three pairs above are mistakenly killed.
But we can add them back manually later.
