[X86][3DNow!] Enable commutation for PFADD/PFMUL/PFCMPEQ/PAVGUSB/PMULHRW
...
All commutations confirmed to give identical results - note PFMAX/PFMIN do not
PFSUB<->PFSUBR should be commutable as well

Added 0x0D to 2-byte opcode extension table for prefetch* variants
...
Fixed decode of existing 3dNow prefetchw instruction
Intel is scheduled to add a compatible prefetchw (same encoding) to future CPUs

add support for the prefetch/prefetchw instructions, move femms into
...
the right file. The assembler supports all the 3dnow instructions now,
but not the "3dnowa" ones.

what the heck, add support for the rest of the 3dNow! binary operations.

Implement support for the bizarre 3DNow! encoding (which is unlike anything
...
else in X86), and add support for pavgusb. This is apparently the
only instruction (other than movsx) that is preventing ffmpeg from building
with clang.
If someone else is interested in banging out the rest of the 3DNow!
instructions, it should be quite easy now.
