This is a low speedup, but the x86 mmx version also gets only ~2x. The mmx version
is also heavily inaccurate, while the vsx version has high accuracy.

Okay, so I'm a bit unsure what to do here. I'm sure it could be faster if made as
inaccurate as the mmx version, but that differs a lot from the C version, which itself
is inaccurate vs the _full C and vsx versions. There are no other versions than mmx and
C to compare against.
I took the approach of using the accurate _full YUV logic, just writing two pixels for
each UV value. The C version uses a LUT, resulting in ~1/255 rounding errors in most
pixels compared to the accurate C/VSX _full logic. The MMX version does low accuracy
logic, differing from the C LUT as much as 10/255 per pixel.
Speed or accuracy? IMHO the mmx errors are far too large.
