This could happen during golden overlay frame coding from a previous
alt-ref frame if the special overlay code was triggered.

vp9_init_quantizer() is called in vp9_create_compressor(), and
should not be called in vp9_set_speed_features().

* changes:
  Removing two unused arguments from vp9_inc_mv signature.
  Changing signature of vp9_get_pred_probs_tx_size.

Encoding of first 50 frames of bus (speed 0) @ 1500kbps goes from
1min6.2 to 1min5.9, i.e. 0.5% faster overall.

About 15% faster for bus (speed 0) first 50 frames @ 1500kbps, which
goes from 1min36 to 1min24. Results become slightly better (+0.2% on
derf/yt, +0.4% on hd), probably because of a bugfix for skipmode in
super_block_yrd(). Overall speed change (on derfraw300) is roughly
-13%. This can probably be improved further by caching best_yrd
between partition searches. Also, we might be able to get more
speedups by always doing PARTITION_NONE before PARTITIONS_SPLIT, not
just at the sb8x8 level.

+0.2% SSIM and glbPSNR on derfraw300.

Current partition checking starts from small sizes, and then goes up
to large sizes. This experiment uses the small partitions' motion
estimation result, which is already available, to speed up the
large partition's motion estimation. We can decide to skip some
patition checkings if they are unlikely choices. We could use the
motion vector(MV) result as current partition's prediction MV, limit
the search range and reference frame.

Current result at speed 1:
psnr loss: 1.19% for stdhd, 0.287% for derf.
speed gain: 14% for sunflower(hd), 11% for akiyo.

Further improvement will be done later.

Call the individually optimized horizontal and vertical functions. This
implementation abuses the temp buffer.

This will be replaced with a custom optimized function.

Over 2x speedup.

Use an estimate based on DC_PRED for intra uv cost
within the rd loop then only do a full uv mode analysis
if an intra mode is chosen.

Significant speed gains in some cases. Currently only
enabled for speed 2 pending speed/quality tests.
