With row-tile enabled, the encoder test driver needs to configure the
decoder in order to decode all tiles correctly.

dequantization modes.
Reduced number of different dequantization modes from 5 to 3.
Changed dequant_val_nuq to be allow for 3 dequant levels instead of 1.
Fixed lint errors

Implements wedge mask generation by pre-computing arrays.
Improves encode speed by 15-20%.
Also consolidates the mask generation code for inter-inter
and inter-intra.

In large-scale tile coding, when the number of tiles is large and the tile
size is small, using a fixed number of bytes in the tile header to store
tile-data size information as done in current VP9 codec would bring high
overhead for each tile. This patch implemented 2 ways to lower that overhead
and adaptively determine the number of bytes needed for tile-data size
transmission.
The test on a test clip having the tile size of 64x64 showed that the number
of bytes used for storing tile-data size was reduced from 4 to 1, which
substantially improved the compression ratio in large-scale tile coding.

A small gain (0.1 - 0.2%) with this experiment on derflr/hevcmr.
The DST2 can be implemened very efficiently using sign flipping
of odd indexed inputs, followed by DCT, followed by reversal of
the output. This is how it is implemented in this patch.
SIMD optimization is pending.

Includes tests which compare output of new SSSE3 functions with
their C equivalents, and fixes to the C code to ensure these tests
pass.

Changes ensure wedge_partition, interintra and palette expts all
work alongside the ext_coding_unit_size experiment.

When the error resilient mode is on, the decoder resets mode info structure
to zero once per frame. This makes decoder about 10x slower if we decode
a single tile at a time. This patch resolves the issue by only memset mode
info of those decoded tiles. Currently, to decode a frame, tile decoding is
less than 2x slower than frame decoding.

This is a port of 4f5108090a6047d5d4d9ce1df302da23b2ef4bc5
This commit also fixes a bug where FLIPADST transforms when combined
with a DST (that is FLIPADST_DST and DST_FLIPADST) did not actually did
a flipped transform but a straight ADST instead. This was due to the C
implementation that it fell back on not implementing flipping. This is
now fixed as well and FLIPADST_DST and DST_FLIPADST does what it is
supposed to do.
There are 3 functions in the SR_MODE experiment that should be updated,
but given that the build of SR_MODE is broken at the upstream tip of
nextgen, I could not test these, so I have put in assertions and FIXME
notes at the problematic places.
