Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.

I couldn't measure it to be slower for normal interframe videos.
For the worst case, high-bitrate intra-only videos, it can be 0.7% slower.

These macros are redundant.  All uses are replaced with the generic
DECLARE_ALIGNED macro instead.

This is generally around 12% faster than the prior method of creating a
linked list for each block as tokens are read, but can be anywhere from
8% to 28% faster depending on file and CPU.

This increases the slice size to 64 pixels, due to having to decode an
entire chroma superblock row per slice.

This can be up to 6% slower depending on clip and CPU, but is necessary
for future optimizations that gain significantly more than was lost.

No measurable speed difference

This doesn't really matter yet since 4:2:0 1080p has only 3060 superblocks,
but larger resolutions or 4:4:4 1080p could hit this case.

No speed difference, but it will simplify the special 4129 case.

Much faster for long runs (e.g. nearly uncoded frames), slightly faster
for the general case.
