Deb Mukherjee 2b26cf1786 Adds feature for companded MV encoding 
The high-precision (1/8) pel bit is turned off if the reference
MV is larger than a threshold. The motivation for this patch is
the intuition that if motion is likely large (as indicated by
the reference), there is likley to be more motion blur, and as
a result 1/8 pel precision would be wasteful both in rd sense
as well as computationally.

The feature is incorporated as part of the newmventropy experiment.
There is a modest RD improvement with the patch. Overall the
results with the newmventropy experiment with the threshold being
16 integer pels are:

derf: +0.279%
std-hd: +0.617%
hd: +1.299%
yt: +0.822%

With threshold 8 integer pels are:

derf: +0.295%
std-hd: +0.623%
hd: +1.365%
yt: +0.847%

Patch: rebased
Patch: rebase fixes
