070ce7efad vp8: add do { } while(0) around XCHG() macro to avoid confusing if/else
This is the correct solution to the warning "fixed" in the previous
commit.

libavcodec/vp8.c:892: warning: suggest explicit braces to avoid ambiguous `else'

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.

7ed06b2be8 Simplify MV parsing, removes laying out 2 or 4 (16x8/8x8/8x16) MVs over all
16 subblocks (since we no longer need that), which should also lead to a
minor speedup.

7c4dcf8165 Optimize split MC, so we don't always do 4x4 blocks of 4x4pixels each, but
we apply them as 16x8/8x16/8x8 subblocks where possible. Since this allows
us to use width=8/16 instead of width=4 MC functions, we can now take more
advantage of SSE2/SSSE3 optimizations, leading to a total speedup for splitMV
filter of about 10%.

d6f8476be4 Make VP8 DSP functions take two strides
This isn't useful for the C functions, but will allow re-using H and V functions
for HV functions without adding separate H and V wrappers.
