84dc2d8afa Remove DECLARE_ALIGNED_{8,16} macros 
These macros are redundant.  All uses are replaced with the generic
DECLARE_ALIGNED macro instead.

c72625f299 Delay translating DCT tokens into coefficients until immediately before IDCT 
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.

7a095ea6fb Do MC and IDCT in coding (hilbert) order 
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.

a89264761f Handle Theora's continued runs in superblock coding. 
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.

e6e32bdc5f Optimize unpack_vectors() by not shuffling around redundant vectors. 
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.

9d8bb0318a Small refactoring: Instead of 4 loops for decoding AC coefficients based 
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().

098523eb28 Use a list to track which fragments coded in this frame still have 
outstanding coefficients yet to be decoded from the bitstream. Once a
fragment reaches end-of-block, remove it from this new list. This change
makes the VP3/Theora entropy decode process dramatically faster due to
not having to iterate incessantly over fragments which have already been
fully decoded.

138fe83215 Perform the DC prediction reversal immediately after decoding all of 
the DC coefficients. This has a greater probability of leveraging the
coefficients while they are still cached.

When testing with the Big Buck Bunny 1080p video, I consistently saw
improvements of 500k-600k dezicycles per run (through
reverse_dc_prediction()) thanks to this move.
