./ffmpeg_g -f rawvideo -pix_fmt rgb24 -s hd1080 -i /dev/zero -pix_fmt yuv420p16be \
-s 1920x1728 -f null -vframes 100 -v error -nostats -

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.

we generally test for build/cpu environment capabilities in configure
and then set stuff like HAVE_MMX / HAVE_MMX_EXTERNAL / ...
and where needed test again at runtime if the actual CPU the code runs
on supports the extension

I dont know if it can happen that code is built where this is supported and
then run where it is not

but this at least looks like it should be tested for by configure
this also allows the user to force them not to be built
