There was a bug in the previous code that if GOLDEN was better than
LAST neither would be used. LAST would get turned off due to superior
GOLDEN quality then all GOLDEN modes would get skipped.

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.

* changes:
  normalize int64_t high value to INT64_MAX
  resolve issue with arm code failing unit test

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.
