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%

defined return type.

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.
