This is to exclude coding CFL for block sizes where it is normatively not allowed. 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. Change-Id: I28712a177853a20c9eb2993e740da8ba7c95a8cc

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%).
