This is to avoid split asm sections that attempt to preserve some
registers between sections.

The 24-bit ydt also should not depend on endianness,
since all of it ends up in a single 32-bit pixel.
This seems likely to be wrong though, since it is different
from the 15 and 16 bit modes and might explain the half-width
issue for 24 bit truemotion.

Since the 24 bit format is decoded to endian-dependant
BGR32 and not BGR24, do not swap red and blue on big-endian
for this format as well.

Rename av_fill_image_max_pixstep() to av_fill_image_max_pixsteps().
