    	x86: cabac: replace explicit memory references with "m" operands

    	This replaces the explicit offset(reg) memory references with
    	"m" operands for the same locations.  As a result, one fewer
    	register operand is needed for these inline asm statements.

This change appears to have broken compilation on darwin, and subsequent
fixes by martin (which did not fix compilation) removed the register
advantage, thus this change seems not a good idea to keep.

Fixes ticket #883

FourCC CYUV can be Creative YUV and uyvy422 rawvideo.

Fixes ticket #878.

This issue was discovered while decoding the FATE sample vqa/ws_snd.vqa.
For some unknown reason only audio decoding is tested by FATE for that file,
but not video.

Not all applications (e.g. MPlayer) set block_align, and
when using a different demuxer it might not even be
easily available.
So fall back to selecting mode based on bit rate as before
if block_align has not useful value.
It can't be worse than failing to decode completely.
