However, this will reduce the combinations of filter types needed to search in

av1_find_mv_refs sets the ALL_ZERO flag when either (a) we don't have
enough candidate MVs, or (b) all candidate MVs are zero. With global
motion enabled, case (b) does not work as intended and causes two
problems: a significant quality decrease for foreman_cif.y4m, and
test failures in *CpuSpeedTest*Screencast*.

This patch skips check (b) when global motion is enabled, fixing
the above bugs.

This is added as part of ALT_INTRA experiment.

This uses interpolation between top row and estimated bottom row; as
well as left column and estimated right column to generate the
predicted block.The interpolation is done using a predefined weight
array.

Based on experiments, the currently chosen weight array was created
to represent a quadratic curve, but can be tuned further if needed.

Improvement from baseline on Derf set:
ALL Keyframes: 1.279%

Improvement from existing ALT_INTRA:
ALL Keyframes: 1.146%

Fix a case in rdopt where a block's mode would be set to ZEROMV but
its motion vector would not be set to the global motion vector.
This caused future inter frames' lists of candidate mvs to become
desynchronized between the encoder and the decoder.

This commit adds initialization for tmp_rd_stats, to resolve valgrind

This commit fixes the use of uninitialized value in the RD search
loop. It brings back the coding performance loss when the above
three experiments are all turned on.

The recursive transform block partitioning system naturally supports
the use of rectangular transform block size. Hence there is no need
to make a separate coding route for the rectangular transform block
size support there.

Fix a case where handle_inter_mode could return without restoring
the original values of xd->plane[i].dst.buf. This fixes an
assertion failure in aom_blend_a64_mask, as well as very slightly
improving the rd costing accuracy.

This commit re-synchronize the reference frame type use cases in

Change-Id: Ib25231c716db4176cd67cbdc889472a06b607194

Adds a feature to recode if global motion is used for a reference but
has very few blocks in the frame actually using it.

lowres improves to -0.512% on average.

1. block_rd_txfm() : av1_optimize_b() should not be called
if pvq is enabled.
Setting t_above and t_left is missing when pvq is enabled,
so added.

2. dist_block() : The nextgen2v has new feature of computing
distortion in pixel domain for speed level = 0, 1, where pvq
works incorrectly since it requres the blank destination
buffer (w/o adding predicted pixels) passed to
inverse trasnform function.

Probably these are missed while negenv2 is merged.
This patch does not fix the regression yet.
