Making foreach_transformed_block_in_plane more clear (it's not finished
yet). Using explicit tx_size variable consistently instead of
(ss_txfrm_size / 2) or (ss_txfrm_size >> 1) expression.

Change-Id: I1b9bba2c0a9f817fca72c88324bbe6004766fb7d

Adding const to above and left pointers. Cleanup.

Change-Id: I51e195fa2e2923048043fe68b4e38a47ee82cda1

Don't do vertical or horizontal splits if subsize < min_partition_size,
except for edge blocks where it makes sense.

Change-Id: I479aa66ba1838d227b5de8312d46be184a8d6401

Refactor choose_largest_txfm_size_ and make it find the largest
transform size via lookup table.

Change-Id: I685e0396d71111b599d5367ab1b9c934bd5490c8

Delete unused / commented out  variable references.

Enable SSE2 implementation of high precision 32x32 forward DCT. The
intermediate stacks are of 32-bits. The run-time goes down from
32126 cycles to 13442 cycles.

Change-Id: Ib5ccafe3176c65bd6f2dbdef790bd47bbc880e56

Remove unnecessary conditional branches in model-based transform
size search.

Adding function build_inter_predictors_for_planes to build inter
predictors for specified planes. This function allows to remove
condition "#if CONFIG_ALPHA" and use MAX_MB_PLANE for general case.
Renaming 'which_mv' local var to 'ref', and 'weight' argument to 'ref'.

Change-Id: I1a97160c9263006929d38953f266bc68e9c56c7d

Reusing existing functions, using constants instead of magic numbers.

Change-Id: Idc689ffba52c9a8b203fcf26bd67110ecb5635f9

Loop filter level moved to common but this case missed.

The lf struct is now with VP9_COMMON, instead of MACROBLOCKD.

Change-Id: Idfdd4f91f78f486078a138322d58bb61e93e1bc9

Adding set_skip_context() function used from both encoder and decoder.

Change-Id: Ia22cfad3211a00a63eb294f64f857b78f4aa9b85

Invert loops to operate vertically in the inner loop.  This allows
removing redundant loads.

Also add preloading of data.

Change-Id: I4fa85c0ab1735bcb1dd6ea58937efac949172bdc

Each iteration of the horizontal loop reuses 7 of the 11 source
values.  Loading only the 4 new values saves some time.

Also add preload for source data.

Overall 4% faster on Chromebook.

There will be another change set to rename BLOCK_SIZE_TYPE enum to
BLOCK_SIZE.

Change-Id: I8d1dfc873d6186fa5e554262f5169e929978085e

It represents the minimum partition size, so don't split if
bsize == min_partition_size .
