b2c087871d Move x86util.asm from libavcodec/ to libavutil/.
This allows using it in swscale also.

c90b94424c 4:4:4 H.264 decoding support
Note: this is 4:4:4 from the 2007 spec revision, not the previous (now deprecated) 4:4:4 mode in H.264.

504811baea Roll back 4:4:4 H.264 for now
Needs some ARM/PPC asm modifications.

d0005d347d Modify x86util.asm to ease transitioning to 10-bit H.264 assembly.
Arguments for variable size instructions are added to many macros, along
with other various changes. The x86util.asm code was ported from x264.

19fb234e4a H.264: split luma dc idct out and implement MMX/SSE2 versions
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.

ae11291865 Unroll loop in h264_idct_add16intra_sse2(). Basically identical to r25171, this
inlines scan8[] and removes loop setup. 15% faster, 0.4% overall.

See "[PATCH] unroll loop in h264_idct_add8_sse2()" thread on ML.

4bca677494 Unroll loop in h264_idct_add8_sse2(). This means we can inline scan8[] in the
code directly also and remove loop setup. 20% faster in function, 0.8% overall.

See "[PATCH] unroll loop in h264_idct_add8_sse2()" thread on ML.

1d16a1cf99 Rename h264_idct_sse2.asm to h264_idct.asm; move inline IDCT asm from
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%.
