Instead of having CLPF write to an entire new frame and
copy the result back into the original frame, make the
filter able to work in-place by keeping a buffer of size
frame_width*filter_block_size and delay the write-back
by one filter_block_size row.
This reduces the cycles spent in the filter to ~75%.

- Unit tests are added for AVX2 SIMD.
- Encoder speed improvement:
AV1 baseline and EXT_TX, three 1080p sequences at bitrate:
800 Kbps, 2 Mbps, 6 Mbps, on i7-6700 CPU, average
user level time reduction: 3.86%.

Move code for reading and writing literals and reading trees to use
just the aom_read_bit() and aom_write_bit() function calls.

(cherry picked from commit 9dd0b89824)
Includes a major refactoring/enhancement to support
tile-adaptive switchable restoration. The framework can be
readily extended to add more restoration schemes in the
future. Also includes various cleanups and fixes.
Specifically the framework allows restoration to be conducted
on tiles such that each tile can be either left unrestored, or
use bilateral or wiener filtering.
There is a modest improvemnt in coding efficiency (0.1 - 0.2%).
Further enhancements will be added subsequently to improve coding
efficiency and complexity.

This commit adds asserts to clarify value ranges in sum computations,
also corrects type conversion used in related calculations.

When the experiment is ON, we use Paeth predictor instead of TM
predictor.
For derf set, this gives about 0.09% improvement overall, and 0.55%
improvement if all frames are forced to be intra-only.
Also, if the EXT_INTRA experiment is also on, the improvement overall
is 0.056%, and improvement if all frames are forced to be intra-only is
0.465%.
