This commit re-designs the per transformed block rate-distortion
costs tracking buffers. It removes redundant buffer usage, makes
the needed context memory allocation per VP9_COMP instance and
reuses the same buffer sets inside the rate-distortion optimization
search loop, thereby avoiding repeatedly requiring memory space.
It reduces speed 0 runtime:
bus at 2000 kbps from 166763ms to 158967ms,
football at 600 kbps from 246614ms to 234257ms.
Both about 5% speed-up. Local tests suggest about 2% to 5% speed-up
for speed 1 and 2 settings. This does not change compression
performance.

Increases these parameters.
There is a small efficiency gain.

The intra mode distortion adjustment for skip_encode feature was
broken in the refactoring cc91851. This commit fixes it and tunes
the distortion models used therein.

Use b_mode_info to store the inter prediction mode of sub8x8 block,
in replacement of the use of partition_info. Remove redundant buffer
update for partition_info. For bus_cif at 2000 kbps, this seem to make
speed 0 about 1% faster.

We already have itxm_add member in MACROBLOCKD structure. Both
inv_txm4x4_1_add and inv_txm4x4_add are just its special cases for
different eob values. But eob logic is already implemented in
vp9_iwht4x4_add and vp9_idct4x4_add (that's why also removing
inverse_transform_b_4x4_add).

For CpuUsed 1 & 2, this commit allow to skip retangular partition check
when NONE is better than SPLIT. It also changed to allow such logic
on alt ref frame coding rather than use square partition all them. The
change has gain compressio about .3% on yt and ythd for both 1&2, It
helped .6% compression on cif and stdhd for both CpuUsed 1&2.

This commit allows sub8x8 intra modes test in the rate-distortion
loop for hd sequences in speed 1 and 2.
For sequence y90n of hd set at 8000 kbps, speed 2 runtime goes
from 207s to 210s. For ped_1080p at 3000 kbps, speed 2 runtim goes
from 336s to 337s. Both are running with 300 frames.
This improves compression performance by 0.24% for stdhd and 0.32%
for hd.
