The probabilities derived from these statistics are used in bitstream
writing; therefore, we should only do this when we actually decide to
use macroblock coding (over superblock coding). Derf gains +0.15%.

Rename pick_mb_modes to pick_mb_mode, since it now handles only a
single macroblock. This is consistent with pick_sb_mode handling a
single non-macroblock.

Use subtract_sb* instead.

Change-Id: I3f34140ab97061063a4452945347ef1fe37e13d1

More specifically, remove vp9_quantize_mb*, vp9_optimize_mb*,
vp9_inverse_transform_mb* and vp9_transform_mb*. Instead, use the
generic _sb* functions that take a size argument, and call them with
BLOCK_SIZE_MB16X16.

With these fixed, the codec produces identical results regardless of
what literal values are used for the enum members in BLOCK_SIZE_*.

The resulting values are never used.

Merge various super_block_yrd and super_block_uvrd versions into one
common function that works for all sizes. Make transform size selection
size-agnostic also. This fixes a slight bug in the intra UV superblock
code where it used the wrong transform size for txsz > 8x8, and stores
the txsz selection for superblocks properly (instead of forgetting it).
Lastly, it removes the trellis search that was done for 16x16 intra
predictors, since trellis is relatively expensive and should thus only
be done after RD mode selection.

Gives basically identical results on derf (+0.009%).

The unified dequantization, inverse transform, and adding functions
support rectangular block sizes. Also separate the operations on
luma and chroma components, in the consideration of the txfm_size
for uv components in rectangular block sizes.

The strategy to run fast loop filter picking for encoder speed-up
should be revisited at a later stage.

Unify the sb32x32 and sb64x64 decoding units, which also allow for
other rectangular block sizes.

Change-Id: Ia5187ab2af56f98c3f99272bdf4dbcabe798ad5d

Merge sb32x32 and sb64x64 functions; allow for rectangular sizes. Code
gives identical encoder results before and after. There are a few
macros for rectangular block sizes under the sbsegment experiment; this
experiment is not yet functional and should not yet be used.

Restructure the code to avoid the majority of per-block-size
