c60ed66dbe Revert r24339 (it causes fate failures on x86-64) - I'll figure out what's 
wrong with it tomorrow or so, then re-submit.

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.

Based on a patch by Loren Merritt <lorenm AT u washington edu>.

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.

b834becdae Pass the composition and ancillary ID for DVB subtitles via extradata instead 
of sub_id, this allows detecting when that information is not available and
just decode everything.
In addition extradata is required for many codecs and thus in contrast to
sub_id generally already passed on by any programs using libav*.
Also ask for a sample if we encounter a stream with multiple/changing IDs.
