      libswscale/ppc: VSX-optimize 9-16 bit yuv2planeX · 8522d219

      ./ffmpeg_g -f rawvideo -pix_fmt rgb24 -s hd1080 -i /dev/zero -pix_fmt yuv420p16be \

      9-14 bit funcs get about 6x speedup, 16-bit gets about 15x.
      Fate passes, each format tested with an image to video conversion.
      
      Only POWER8 includes 32-bit vector multiplies, so POWER7 is locked out
      of the 16-bit function. This includes the vec_mulo/mule functions too,
      not just vmuluwm.

      avutil/ppc/cpu: Fix power8 linux detection · fc6022e1

      The existing code was in no released kernel that I can see. The corrected code
      was added in 3.9.
