[FFmpeg-devel] swscale/swscale_unscaled : add X86_64 (SSE2, AVX) for uyvyto422

[Martin Vignali]

Hello,

New patch in attach,
Remove the C part of the sse/avx func, and integrate all the process in the
ASM func

A little bit faster, and avoid the macro in x86/rgb2rgb.c.

Checkasm result :
uyvytoyuv422_c: 15045.4
uyvytoyuv422_mmx: 14092.4
uyvytoyuv422_mmxext: 21630.2
uyvytoyuv422_sse2: 4452.2
uyvytoyuv422_avx: 4217.9
