Usage of encode_b_args is unnecessary because encode_block_pass1() doesn't
use them. That's why optimize_init_b() call is also not required.

The commit change to use partitions sizes directly from last frame
for frames directly where last frame selects partitions sizes based
on coding efficiency.
On --rt --cpu-used=-5, the change hurts compression by 4% but reduces
encoding time by ~20%

Modify existing test to also check the case of dropping
(i.e., skip decoding) a consecutive list of frames.

This commit builds the actual prediction block in sub-pixel accuracy
and uses which to calculate SAD for non-RD mode decision. In the trail
run on pedestrian_area at 1080p, rtc speed -7 runtime goes from
23495 ms -> 25107 ms (7% slower). The compression performance is
improved by 20.57% for rtc test set.

Use a set of dedicated variables to buffer the current best mode
in non-RD mode decision. This allows to use mode_info for more
complicated test in the non-RD process.

Adds a method for determining a fixed size partition based on
variance of a 64x64 SB. This method is added to rtc speed 6.
Also fixes a bug in rtc_use_partition() and includes some
refactoring related to partitioning search, and some cosmetics.
Currently compared to speed 5, the coding efficiency of speed 6
is -19% and that of speed 7 is -55%, in cbr mode.

The optimizer did something funny with the code around
line 1412. Before the call to encode_sb split_dist was
set properly but after it was adjusted and converted to
a negative.

Change dx_time data type to int64_t to prevent
test time overflow when decoding long video.

If sf->disable_split_mask is DISABLE_ALL_SPLIT, disable
sf->adaptive_pred_interp_filter to avoid unnecessary operations.
