About 2.5x the speed.
NOTE: the way that the asm code handles large qmuls is a bit suboptimal.
If x264-style dequant was used (separate shift and qmul values), it might
be possible to get some extra speed.

suncc does not like the leading commas inside the macro, but it has no problem
with trailing commas.

SSSE3) about ~6-fold, 3.6% faster overall with cathedral sample.

which represents H264DSPContext and is now compiled on its own.

Should fix compilation with icc and should help prevent any future duplicates

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.

These macros are redundant. All uses are replaced with the generic
DECLARE_ALIGNED macro instead.

SVQ1 chroma has been special-cased aligned to 16-bytes since at least r15466
Other architectures also assume 16-byte alignment here too but set STRIDE_ALIGN
to 16.

29-105% faster apply_filter, 6-90% faster ape decoding on core2
(Any x86 other than core2 probably gets much less, since this is mostly due to ssse3 cachesplit avoidance and I haven't written the full gamut of other cachesplit modes.)
9-123% faster ape decoding on G4.
