These large (200 KB) static stables are functionally read-only. Marking
them const moves them to the read-only section of shared libraries,
reducing memory footprint when multiple application processes are
running simultaneously.

4:4:0 has been removed from AV1 profiles, therefore there is no need
to have these files for testing.

This experiment of ref-adapt removes the option of COMPOUND_REFERENCE
from the frame level reference_mode setup, and hence removes 1 bit
in the frame header syntax. It now allows only SINGLE_REFERENCE or
REFERENCE_MODE_SELECT to specify in the frame header.

No noticeable coding performance impact has been observed.

This experiment of frame_sign_bias is to remove the 7 bits in the
frame header that signal the sign bias value for the 7 reference
frames. Instead of explicit signaling, this experiment is to use
the frame_offset value to derive the frame sign bias. It achieves
-0.08~-0.1% coding gain on average. It has been adopted by AOM.

Interintra RDO is moved into motion_mode_rd instead of calling
handle_inter_mode() separately. This will save time on interp
filter and new mv search, also skips interintra modes if the base
inter predictors are not good enough.

Speedup: LL ~20% HL < 1%
Tiny performnace improvements (<0.05%).

The self-guided filter has now been implemented using
the intrinsics for AVX2. The corresponding speed and
correctness tests have also been added.

Note: All AVX2 functions are in synonyms_avx2.h, as
GCC produces 'ABI change' warnings if they are
included in synonyms.h.

If the intrabc motion vectors are invalid or out of range then
this patch defines deterministic decoder behaviour (disabling intrabc).
This will then allow conformance tests to be written to check this
deterministic behaviour so that we do not end up with undefined
behaviour or compatibility problems related to illegal intrabc
motion vectors.

when trellis quantizaiton is disabled, the b_quantizer should be used.
existing code has a lot of hard coded flag not hooked up correctly with
high level trellis quantization enable/disable flag, which causes
fp_quantizer is used. this patch is intended to remove the hard coded
flags and correctly get them from the high level control.

When the coding block size is below 16x16, the current tx size
search loop may end up searching 4x4 transform size multiple times.

frame coding, and 3% for overall.
