Lauri Kasanen 50e672bc54 swscale/ppc: VSX-optimize non-full-chroma yuv2rgb_1

32-bit mul, power8 only.

1.8-2.3x speedup:

rgb24
  18192 UNITS in yuv2packed1,   32767 runs,      1 skips
   9983 UNITS in yuv2packed1,   32760 runs,      8 skips

  20185 UNITS in yuv2packed1,   32768 runs,      0 skips
   8761 UNITS in yuv2packed1,   32761 runs,      7 skips

   8759 UNITS in yuv2packed1,   32764 runs,      4 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.
