e3f7bf774c Fix SPLATB_REG mess. Used to be a if/elseif/elseif/elseif spaghetti, so this 
splits it into small optimization-specific macros which are selected for each
DSP function. The advantage of this approach is that the sse4 functions now
use the ssse3 codepath also without needing an explicit sse4 codepath.

3ae079a3c8 VP8: optimize DC-only chroma case in the same way as luma. 
Add MMX idct_dc_add4uv function for this case.
~40% faster chroma idct.

8a467b2d44 VP8: 30% faster idct_mb 
Take shortcuts based on statistically common situations.
Add 4-at-a-time idct_dc function (mmx and sse2) since rows of 4 DC-only DCT
blocks are common.
TODO: tie this more directly into the MB mode, since the DC-level transform is
only used for non-splitmv blocks?

7dd224a42d Various VP8 x86 deblocking speedups 
SSSE3 versions, improve SSE2 versions a bit.
SSE2/SSSE3 mbedge h functions are currently broken, so explicitly disable them.

b8b231b5dc Make mmx VP8 WHT faster 
Avoid pextrw, since it's slow on many older CPUs.
Now it doesn't require mmxext either.

fb9bdf048c Be more efficient with registers or stack memory. Saves 8/16 bytes stack 
for x86-32, or 2 MM registers on x86-64.

3facfc99da Change function prototypes for width=8 inner and mbedge loopfilter functions 
so that it does both U and V planes at the same time. This will have speed
advantages when using SSE2 (or higher) optimizations, since we can do both
the U and V rows together in a single xmm register.

This also renames filter16 to filter16y and filter8 to filter8uv so that it's
more obvious what each function is used for.

ede1b9665a Give x86 r%d registers names, this will simplify implementation of the chroma 
inner loopfilter, and it also allows us to save one register on x86-64/sse2.

526e831a46 Change return statement, the REP_RET is a mistake since the else case (x86-64, 
sse2) doesn't actually loop, so REP_RET isn't necessary.
