Lauri Kasanen 8dd9df9ecd swscale/output: Altivec-optimize float yuv2plane1 
This function wouldn't benefit from VSX instructions, so I put it
under altivec.

./ffmpeg_g -f rawvideo -pix_fmt rgb24 -s hd1080 -i /dev/zero -pix_fmt grayf32le \
-f null -vframes 100 -v error -nostats -

28608 UNITS in planar1,   65530 runs,      6 skips

The native speedup is 6.28133, and the bswapping one 6.15623.
Fate passes, each format tested with an image to video conversion.
