Simplified the code that extracts and uses the motion
vectors for the 4 sub-partitions in rd_pick_partition.

This commit makes the initialization of trellis coeff optimization
a per-plane operation, thereby eliminating the redundant steps in
encode_sby and encode_sbuv. It makes the encoder at speed 0 slightly
faster.

The feature that uses small partition results as a measure to skip
mode evaluation at larger partition requires the flags to be reset.
The reset was missing in the code path that calls rd_use_partition().

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.

Adding plane type check condition because it was always used outside of
get_tx_type_{4x4, 8x8, 16x16}.

Although local copies of the mode member variables
(mode, ref_frame) were made, they were not used in
all places. Also, made a local copy of the
second_ref_frame member.

Prevents doing duplicate IDCTs; encoding of first 50 frames of bus
(speed 0) @ 1500kbps goes from 1min4.0 to 1min3.5, i.e. 0.87% faster
overall.

Encoding time of first 50 frames of bus (speed 0) @ 1500kbps goes from
1min5.4 to 1min4.0, i.e. 2.2% faster overall.

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

The struct optimize_block_args is defined same as encode_b_args.
Remove this redundant definition, and use encode_b_args consistently.

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

The xform_quant() module is only used by inter modes, hence removing
the redundant switches therein conditioned on tx_type.

When all the transform coefficients were quantized to zero, skip
the inverse transform operation. For bus_cif at 1000 kbps, the
runtime goes from 154967ms -> 149842ms, i.e., about 3% speed-up,
at speed 0.
