This patch allows the encoder to directly split the block
in partition search, therefore skip searching NONE. It
computes a score which measures whether 16x16 motion vectors
from the first pass in the current block are consistent with
each others. If they are inconsistent and we have enough Q
to encode, split the block directly, and skip searching NONE.

This feature is under flag CONFIG_FP_MB_STATS. In speed 2,
it further gives a speedup of 3-8% on sample yt clips as
compared to the previous version under the same flag. Overall,
the features under the flag will give 7-15% on typical yt
clips at up to 6000kbps data rate. The speedup at very high
data rate is not significant.

For hard stdhd clips:
park_joy_1080p @ 15000kbps:       504541ms -> 506293ms (-0.35%)
pedestrian_area_1080p @ 2000kbps: 326610ms -> 290090ms (+11.2%)

The compression performance using the features under the flag:
derf: -0.068%
yt:   -0.189%
hd:   -0.318%
stdhd:-0.183%

To use the feature, set CONFIG_FP_MB_STATS and turn on
cpi->use_fp_mb_stats.

This code was being called from two places and
difficult to parse. I rationalized it in to a
function to improve readability.

Merge "[spatial svc]Enabl golden frame for base layer and fix wrong ref_frame_flag for upper layers in first frame"

* changes:
  vpxdec warning errors addressed
  cast enums to int to avoid gcc warning in pred_common

Re-organize the one-byte structure for 16x16 first pass
