ppc: swscale: rework yuv2planeX_altivec()
...
This gets rid of the variable-length scratch buffer by filtering 16
pixels at a time and writing directly to the destination. The extra
loads this requires to load the source values are compensated by not
doing a round-trip to memory before shifting.

Fix destination row striding in altivec_yuv2_bgr24.
...
Misaligned row artifacts showed up when a 624x352 frame was converted
to BGR24 format. When advancing to the next row the destination linesize
was added to the last output pointer position which was not linesize aligned,
resulting in a distorted picture.

This allows using more specific implementations for chroma/luma, e.g.
we can make assumptions on filterSize being constant, thus avoiding

It just does that part in scalar form, I doubt using a vector store
