Try and cut down the cycle count by rearranging the instructions
so there are less stalls.

Update logic for both mode and mvref was the same, so using MODE_COUNT_SAT,
MODE_MAX_UPDATE_FACTOR, update_ct, update_ct2 for both cases. Removing
function update_tx_ct because it was identical to update_mode_ct2.

Stack the rate-distortion statistics in the sub8x8 rd loop. This allows
the encoder to skip the forward transform, quantization, and coeff cost
estimation, in the sub8x8 rd optimization search, if the motion
vector(s) are of integer pixel value, and have been tested in the
previous prediction filter type rd loops of the same block.

This gives about 2% speed-up for bus_cif at 2000 kpbs, for speed 0.
Its efficacy depends how frequently the motion search will select an
integer motion vector.

Mode search order in rd loop changed to better reflect
observed hit counts.

Also some adjustment of the baseline mode rd thresholds
to reflect the order change and observed frequencies.

This cl fixes issues rbultje brought up. that I somehow neglected when I

When CONFIG_POSTPROC is set there was a now
invalid reference to cm->filter_level.

Changed to cpi->mb.e_mbd.lf.filter_level in line with
change Iaf5fb71c33719cdfa1b991f671caf071be9ea035

This commit allows the encoder to skip a few buffer update steps in
rd_pick_best_mbsegmentation, when early breakout has been triggered
in the rd_check_segment_txsize. It provides about 1% speed-up for
bus_cif at 2000 kbps, in the settings of speed 0.

At speed 2, due to the threshold scheme used, it is possible the rate
and distortion assigned with INT_MAX value. The patch added checking
to prevent the INT_MAX value is used in further calculation of RD
scores. The patch also changed the assertion in rd_use_partition() to
be mirror similar assertion in rd_pick_partition().

Adding loopfilter struct with fields from MACROBLOCKD and VP9Common.
Eventually it will be moved to vp9_loopfilter.h for better code structure.

Changing fc->tx_probs back to fc->pre_tx_probs. This change actually
affects the bitstream but current test vectors work. Chrome branch is not
affected at all. Broken since:

cc662dd7 Adding struct tx_probs and struct tx_counts to cleanup the code.

This patch modifies the auto_mv_step_size speed feature to
use a combination of the maximum magnitude mv from the last
inter frame, and the maximum magnitude mv for the two reference
mvs with the same reference. For arf frames, the max mav step
for the resolution is used.
The bounds therefore are slightly tighter. The feature is made
a speed 1 feature.

Rebased.

Results (when this feature is turned on over speed 0):
derfraw300: -0.046% psnr, about 5+% speedup
(tested on football: goes from 4m30.760s to 4m17.410s).
