45549339bc vp8: disable mmx functions with sse/sse2 counterparts on x86-64.
x86-64 is guaranteed to have at least SSE2, therefore the MMX/MMX2
functions will never be used in practice.

d0005d347d Modify x86util.asm to ease transitioning to 10-bit H.264 assembly.
Arguments for variable size instructions are added to many macros, along
with other various changes. The x86util.asm code was ported from x264.

b1c32fb5e5 Use "d" suffix for general-purpose registers used with movd.
This increases compatibilty with nasm and is also more consistent,
e.g. with h264_intrapred.asm and h264_chromamc.asm that already
do it that way.

827d43bb9d VP8: move zeroing of luma DC block into the WHT
Lets us do the zeroing in asm instead of C.
Also makes it consistent with the way the regular iDCT code does it.

6341838f3c Use word-writing instead of dword-writing (with two cached but otherwise
unchanged bytes) in the horizontal simple loopfilter. This makes the filter
quite a bit faster in itself (~30 cycles less on Core1), probably mostly
because we don't need a complex 4x4 transpose, but only a simple byte
interleave. Also allows using pextrw on SSE4, which speeds up even more
(e.g. 25% faster on Core i7).

2208053bd3 Split pextrw macro-spaghetti into several opt-specific macros, this will make
future new optimizations (imagine a sse5) much easier. Also fix a bug where
we used the direction (%2) rather than optimization (%1) to enable this, which
means it wasn't ever actually used...

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.

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?

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.
