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.
