Enabling SEPARATE_GLOBAL_MOTION will remove the ability for
a block that uses zeromv with global motion to pick warped_causal
or obmc_causal as the motion mode. When this is enabled there is:

0.05% drop on lowres for global + warped enabled
0.15% drop on midres for global + warped enabled

0.12% drop on lowres with global + motion var enabled
0.07% drop on midres with global + motion var enabled
No performance change for global, warped, or motion var individually.

The initial CDF for each frame is stored in
the frame context. CDFs for actual coding are
stored in the tile structures, and these are
what get adapted. The initial CDF is replaced
by an average CDF derived from these tile CDFs.
This is carried forward to future frames when
backward adaptation is on.

CDFs are no longer set from the 8 bit probabilities
in backwards adaptation.

For now, 8 bit probabilities are maintained for
use in the encoder and for symbols which do not
have a CDF.

cause negligible loss (+0.03% BDR) in the current default

can be omitted from the last tile in every tile group.

* code the palette color index using 45 wavefront
* interleave the coeff and palette color index in
  transform block level
* the above change does not change code efficiency

Details: 
The 45 wavefront scan allows to compute the ctx of
the diagonal samples' indices  at the same time. 
Interleaving palette indices and palette residual
on a transform block basis means that the entropy
 decoding and further processing of the palette 
residual is not delayed by the entropy decoding 
of all the color indices of the palette encoded 
block.

Since gm_get_motion_vector is trying to give a motion vector for
"the frame as a whole", it makes more sense for it to calculate
the motion of the *center* of the block rather than the top-left
corner of the frame.

In theory, this change should also help the encoder make better
decisions on when to use global motion. It avoids an issue
where, early in the frame, NEARESTMV looks like a good way to use
the global motion vector *without* paying the rate cost applied
to the first few global motion blocks in each frame. This seems
to lead to a better overall result.
