Arguments for variable size instructions are added to many macros, along
with other various changes. The x86util.asm code was ported from x264.
Signed-off-by: Diego Biurrun <diego@biurrun.de>
About 2.5x the speed.
NOTE: the way that the asm code handles large qmuls is a bit suboptimal.
If x264-style dequant was used (separate shift and qmul values), it might
be possible to get some extra speed.

inlines scan8[] and removes loop setup. 15% faster, 0.4% overall.

code directly also and remove loop setup. 20% faster in function, 0.8% overall.

h264dsp_mmx.c to h264_idct.asm (as yasm code). Because the loops are now
coded in asm instead of C, this is (depending on the function) up to 50%
faster for cases where gcc didn't do a great job at looping.
Since h264_idct_add8() is now faster than the manual loop setup in h264.c,
in-asm idct calling can now be enabled for chroma as well (see r16207). For
MMX, this is 5% faster. For SSE2 (which isn't done for chroma if h264.c does
the looping), this makes it up to 50% faster. Speed gain overall is ~0.5-1.0%.
