James Almer	5750d6c5e9	x86: move XOP emulation code back to x86inc Only two functions that use xop multiply-accumulate instructions where the first operand is the same as the fourth actually took advantage of the macros.

James Almer	3f3d748cab	x86: Move XOP emulation to x86util We need the emulation to support the cases where the first argument is the same as the fourth. To achieve this a fifth argument working as a temporary may be needed. Emulation that doesn't obey the original instruction semantics can't be in x86inc.
