Reuse the alternate CDFs from the --disable-cfl path.

The motion vector search result at single reference frame mode is stored
for later use. There are some issues in current implementation.
1. single_newmv is only stored for 1st ref_mv, but not for other ref_mv
values tested.
2. If single reference mode is skipped and not tested, single_newmv is
not available.
3. Interintra mode always use single_newmv as its MV, which may not be
available as mentioned above.
To fix it, we store single_newmv for every ref_mv tested. In interintra
mode, if single_newmv is not available, do motion search to find a MV.

This was revealed by a motion vector unit test failure.

The superres upscale process only generates cm->height many rows
of pixels, but we were previously using cm->mi_rows*MI_SIZE many.
The latter number are easily available before upscaling, but we
ideally don't want to have to upscale extra rows. So we switch
to only using cm->height many rows inside loop-restoration.

While making this change, I found and fixed an issue with
av1_get_tile_rect() when using horizontal subsampling + horizontal
superres.

Finally, note that this change does introduce an edge case which
isn't obvious from the source code. This has been annotated as a
comment in save_deblock_boundary_lines().

Properly support loopfiltering-across-tiles in combination with
superres and/or loop-restoration:

Upscale one tile column at a time, rather than doing the whole
frame at once. This allows us to correctly support the loop filter
across tiles flag, by temporarily extending the left/right boundaries
of each tile column to avoid sampling from adjacent tiles.

This code is also reused by striped-loop-restoration, when upscaling the
deblocked context above/below each stripe. That way, we i) ensure
that the upscaling is done consistently, and ii) fix the last remaining
case where loop-restoration didn't respect the loop filter across tiles
flag.

This also makes it easy to perform extension of the left/right edges
of the frame "as needed", so we don't need to extend the frame borders
immediately after deblocking. This should give marginally better CDEF
filtering for frames using superres.

REFERENCE_MODE_SELECT to specify in the frame header.

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.

Tiny performnace improvements (<0.05%).
