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.

Inspired by guidance from Dark Shikari. On a Core 2 Duo 2.0 GHz, this
change decodes the 10-minute Big Buck Bunny 1080p short about 2 seconds
faster.

Faster checks in reverse_dc_prediction.
Simplified deblocking checks.
Check transform==15 first, since it's more common than 13.

on their grouping, create one loop that indexes into a table of AC VLC
tables.

There is also a small optimization here: Do not call unpack_vlcs()
if there are no fragments in the list with outstanding coefficients.
My profiling indicates that this can save upwards of 1 million
dezicycles per frame throughout the course of unpack_dct_coeffs().
