Remove top node optimization.
The improvement this gives is not sufficient to justify
the extra complexity.

This commit enables rectangular block prediction of compound
inter-intra mode. It combines the mb/sb32/sb64 prediction functions
into a unified version with configurable block width and height.
This fixes the enc/dec mismatch of the codebase when
comp-interintra-pred is enabled.

Also use explicitely named enum values in sb_type comparisons, rather
than relying on absolute integer values, because enum values may
change in the future.

First in a series of commits making certain MACROBLOCK members
addressable per-plane. This commit also refactors the block subtraction
functions vp9_subtract_b, vp9_subtract_sby_c, etc to be
loops-over-planes and variable subsampling aware.

Adds an experiment that codes an end-of-orientation symbol
for every eligible zero encountered in scan order.
This cleans out various other sub-experiments that were part
of the origiinal patch, which will be later included if found
useful.
Results are slightly positive on all sets (0.1 - 0.2% range).

Removes the redundant dst pointers from vp9_build_inter_predictors_sb{y,uv}
and the remaining mb specific functions.

Wherever there are real pixels available before falling back to use
assumed values 127 and 129.
This also make DC_PRED for i4x4 consistent with DC_PRED for larger
blocks.

First in a series of commits moving the framebuffers pointers to
per-plane data, so that they can be indexed numerically rather than
by name.

For 1080 material, this buffer is currently 2,270,928 bytes. This patch swaps
ptrs instead of copying and uses the last show_frame flag instead of setting
the entire buffer to zero. For the test clip used, the decoder improved by up
to 1%.

Remove the unnecessary _s_ from their names, and add a new
vp9_recon_sb() that calls the y and uv variants.

Similar to the prior change that removed the rounding from non-SPLITMV
modes. Improves quality by a similar amount (Additional +0.087% on derf)
