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.

blocks are common.

only used for non-splitmv blocks?

6526976f0c Remove FF_MM_SSE2/3 flags for CPUs where this is generally not faster than 
regular MMX code. Examples of this are the Core1 CPU. Instead, set a new flag,
FF_MM_SSE2/3SLOW, which can be checked for particular SSE2/3 functions that
have been checked specifically on such CPUs and are actually faster than
their MMX counterparts.

In addition, use this flag to enable particular VP8 and LPC SSE2 functions
that are faster than their MMX counterparts.

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.

ba87f0801d Remove explicit filename from Doxygen @file commands. 
Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.

4693b031a3 Move H264 dsputil functions into their own struct 
This moves the H264-specific functions from DSPContext to the new
H264DSPContext.  The code is made conditional on CONFIG_H264DSP
which is set by the codecs requiring it.

The qpel and chroma MC functions are not moved as these are used by
non-h264 code.

This moves the DWT functions from snow.c and dsputil.c to a file of
their own.  A new struct, DWTContext, holds the function pointers
previously part of DSPContext.

Other architectures also assume 16-byte alignment here too but set STRIDE_ALIGN
