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.

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}.

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.

Several consecutive for loops executed over the same
index range, so I rolled them into one.

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.
