Add SSE2 implementation to handle the special case of inverse 2D-DCT
where only DC coefficient is non-zero.

Adding common merge_probs and merge_probs2 functions. Changing ints to
usigned ints in some places.
Change-Id: Icf088ffdea7cf5b95284a128916409bdd53506b0
Adding plane type check condition because it was always used outside of
get_tx_type_{4x4, 8x8, 16x16}.

Counts are separate from frame context. We have several frame contexts but
need only one copy of all counts.

All filters are interpolating now, so we don't need this array, all
values from this array are evaluated to true.

many structures use bw and bh and they have different meanings. This cl attempts
to start this clean up and remove unneccessary 2 step look up log and then
shift operations...
also removed partition type multiple operation code in bitstream.c.

Renamed:
MAX_MB_SEGMENTS to MAX_SEGMENTS
MB_SEG_TREE_PROBS to SEG_TREE_PROBS
The minimum unit for segmentation in the segment map
is now 8x8 so it is misleading to use MB_ as macro-block
traditionally refers to a 16x16 region.

Moving common encoder/decoder code to update_tx_counts. Also renaming
vp9_get_pred_probs_tx_size to get_tx_probs2 and adding get_tx_probs to
call vp9_get_pred_context_tx_size inside read_selected_tx_size only once
(twice before).

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.
