~2x speedup:

  24431 UNITS in yuv2packed2,   16384 runs,      0 skips
  13783 UNITS in yuv2packed2,   16383 runs,      1 skips

  13124 UNITS in yuv2packed2,   16384 runs,      0 skips

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.
