Justin's version has more features but is otherwise equivalent from the
point of view of the syntax.

Spotted by ubitux.

Improve consistency/readability.

Avoid one dereference, simplify.

Fix crash, for example in the command:
ffmpeg -f image2 -vcodec pgmyuv -i tests/vsynth1/%02d.pgm \
  -vf "[in]format=yuv420p,split,alphamerge,split[o3][o4];
       [o4]vflip,alphaextract[alpha];[o3][alpha]alphamerge[out]" \
  -vcodec rawvideo -f nut md5:

The code causes uninitialized data copy, and may be actually slower than
a loop over each line in case the padding is big.

Such packets are useless.

This is consistent with usual ARM nomenclature as well as with the
VFPV3 and NEON symbols which both lack the ARM prefix.
