Reduce the length of inter_tx_size[] from 1024 to 16.

On a cif test sequence,
encoder memory consumption decreases by 18% (380MB -> 312MB);
decoder memory consumption decreases by 56% (21.4MB -> 9.4MB).

(1) Explicitly reset RD stats for each partition.

Earlier,
PARTITION_SPLIT was the only one resetting the RD_STATS in 'sum_rdc'.

But this was working because:
- PARTITION_SPLIT was tried before VERT, HORZ, VERT_4 and HORZ_4; and
- RD cost calculations in VERT, HORZ, VERT_4 and HORZ_4 partitions
implicitly discarded existing value in sum_rdc

However, that was very fragile; explicitly resetting the stats every
time is much safer.

(2) Using a separate variable 'temp_best_rd_cost' was fragile as someone
may forget to update the same. So, we use best_rdc.rdcost directly.

BUG=aomedia:1271

As per the linked bug report, the distance-weighted compound
prediction has two separate round operations, first by 3
bits (inside the various convolve functions), then by 10 bits
(after the convolution functions).

We can improve on this by right shifting by 3 bits inside the
convolve functions - this is equivalent to doing a single round
by 13 bits at the end.

Note: In the encoder, when doing joint_motion_search(), we do
things a bit differently: So that we can try modifying the two
"sides" of the prediction independently, we predict each side as
if it were a single prediction (including rounding), then blend
these single predictions together.

This is already an approximation to the "real" prediction, even
in the non-jnt-comp case. So we leave that code path as-is.

The comment was misleading as the codec always supports 8-bit,
regardless of the value of CONFIG_LOWBITDEPTH.
This flag just enables the optimized-for-8-bits pipeline,
without changing the actual YUV output.

Speed up recursive transform block partition search. When a txfm
block is selected as all zero coefficients, skip the search over
further split partition.

Tested with txk-sel on, this makes the speed 0 / 1 both 10 - 15%
faster at medium - high target bit-rate range. The coding
performance change is neutral - 0.011% better for lowres set.

The tg_horz_boundary flag should always be 0 for the topmost
tile row, even when dependent-horztilegroups is enabled.
Otherwise, we end up trying to fetch data off the top of the
frame, which results in segfaults.

1) For encoder speed, overall ~1% faster with no impact on coding performance.
2) aom_comp_mask_pred_ssse3 is 3.5x - 6x faster than aom_comp_mask_pred_c
3) aom_comp_mask_upsampled_pred_ssse3 1.5x - 3x faster than
aom_comp_mask_upsampled_pred_c, for special case where subpel_x ==
subpel_y == 0, optimized version achieves 4x - 7x speedup

Unittest for both functions have been added.

Continued to remove count accumulation in decoder for decoder speedup.

Change-Id: I9e3b874bfc5f750297070235bdfc4d71526ed665

In the decode side, frame count accumulation is still existing. This
patch removed part of them. More patch will follow. This should speed up
the decoder.

This doesn't change the encoder side since the counts are useful in
some encoder optimizations.
