vp9_dequantize_x86 has only sse2 functions.
vp9_dct_sse2_intrinsics has no namespace collision and can drop
_intrinsics.
vp9_idct_mmx.h is unused.

Remove similarly named header file. It is obsolete.
Move file to match naming style.
Adjust make file to include the file correctly and remove extra
unnecessary #if guard.

Clean Windows build warnings:
warning C4028: formal parameter <N> different from declaration
This was fixed independently in master and experimental but the fixes
were in opposite directions. One added const to the declaration and the
other removed it from the implementation.
Also update the variable names. This doesn't modify the data so call it
ref, matching the functions in the vicinity, rather than dst.

Fix warning on windows: signed/unsigned mismatch on lines 415, 454
Comparison was between size_t data_sz >= int index_sz on 415 and
unsigned int data_sz >= int index_sz on 454. Both might be changed to
size_t but that would be tracing and replacing all comparisons is
outside the scope of this change.
In the rest of these two functions ensure unsigned values are used
consistently.

Rename the file and clean up includes. In the future we would like to
pattern match the files which need additional compiler flags.

This threshold effectively limits the amount of motion
from one end of a GF/ARF group to the other.
This patch makes the threshold depend on image size.

Extracting setup_frame_size and update_frame_context functions. Introducing
vp9_read_prob function as shortcut for (vp9_prob)vp9_read_literal(r, 8).

Wrote sse2 version of vp9_short_idct_32x32 function. Compared
to c version, the sse2 version is 5X faster.

This gains about 0.2% on derf, 0.1% on hd and 0.4% on stdhd. I can put
this under an experimental flag if wanted, just trying to get my patch
queue in shape.

Adds an experiment to use a weighted prediction of two INTER
predictors, where the weight is one of (1/4, 3/4), (3/8, 5/8),
(1/2, 1/2), (5/8, 3/8) or (3/4, 1/4), and is chosen implicitly
based on consistency of the predictors to the already
reconstructed pixels to the top and left of the current macroblock
or superblock.
Currently the weighting is not applied to SPLITMV modes, which
default to the usual (1/2, 1/2) weighting. However the code is in
place controlled by a macro. The same weighting is used for Y and
UV components, where the weight is derived from analyzing the Y
component only.
Results (over compound inter-intra experiment)
derf: +0.18%
yt: +0.34%
hd: +0.49%
stdhd: +0.23%
The experiment suggests bigger benefit for explicitly signaled weights.

These are mostly just for experimental purposes. I saw small gains (in
the 0.1% range) when playing with this on derf.
