Jason Garrett-Glaser	4f717c69ed	idct_dc for VC-1/WMV3 decoder; ~11% faster decoding overall. Includes mmx2 asm for the various functions. Note that the actual idct still does not have an x86 SIMD implemtation. For wmv3 files using regular idct, the decoder just falls back to simple_idct, since simple_idct_dc doesn't exist (yet).

idct_dc for VC-1/WMV3 decoder; ~11% faster decoding overall.

Includes mmx2 asm for the various functions.
Note that the actual idct still does not have an x86 SIMD implemtation.
For wmv3 files using regular idct, the decoder just falls back to simple_idct,
since simple_idct_dc doesn't exist (yet).

Rename libavcodec/i386/ --> libavcodec/x86/.

It contains optimizations that are not specific to i386 and
libavutil uses this naming scheme already.
