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.

Already defined in vp9_seg_common.h.

Moving code from vp9_adapt_mode_context to vp9_adapt_mode_probs.

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.

Change-Id: I2c6a59e21e5e77b8cf39a4af5eecf4d5ade32e2f

Adding common merge_probs and merge_probs2 functions. Changing ints to
usigned ints in some places.

They share the same functionality, so merging together.

Prior to 73c4e284, the generated .sln files didn't contain any
information about the different configurations when using .vcxproj
project files. The MSVS IDE was able to fill this in just fine when
loaded though.

When building for ARM, the obj_int_extract project still is built
for x86, in order for the build process to be able to use
obj_int_extract.exe.

Now that configuration info is generated, it breaks current ARM
setups, since the configurations generated by gen_msvs_sln.sh only
included configurations from the last parsed project file (as
mentioned in the comment).

In these setups, the MSVS IDE generated a third meta-platform, called
"Mixed Platforms". This meta-platform points to either ARM or
Win32 as platform in each of the individual projects.

When the MSVS IDE generated this automatically, it also included
the original ARM and Win32 platforms as separate choices, but these
can be omitted since they don't make sense.

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.

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.
