x86inc: warn if XOP integer FMA instruction emulation is impossible

Emulation requires a temporary register if arguments 1 and 4 are the same; this
doesn't obey the semantics of the original instruction, so we can't emulate
that in x86inc.

ffmpeg has an x86util emulation for that case; I'll add it if x264's asm ever
needs it.

Also add pmacsdql emulation.
