428aa14a48 x86inc: Make INIT_CPUFLAGS support an arbitrary number of cpuflags 
Previously there was a limit of two cpuflags.

45c7f3997e avutil/pixelutils: faster pixelutils_sad_[au]_16x16 
~560 → ~500 decicycles

This is following the comments from Michael in
https://ffmpeg.org/pipermail/ffmpeg-devel/2014-August/160599.html

Using 2 registers for accumulator didn't help. On the other hand,
some re-ordering between the movs and psadbw allowed going ~538 to ~500.

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.
