c67278098d Move array specifiers outside DECLARE_ALIGNED() invocations

258b60c224 Gcc idiocy fixes related to filter_mb_edge*. 
Change order of operands as gcc uses a hardcoded register per operand it seems
even for static functions
thus reducing unneeded moved (now functions try to pass the same argument in
the same spot).
Change signed int to unsigned int for array indexes as signed requires signed
extension while unsigned is free.
move the +52 up and merge it where it will end as a lea instruction, gcc always
splits the 52 out there turning the free +52 into an expensive one otherwise.
The changed code becomes a little faster.

31f6e3c19e Make calculation of mask_edge free of branches, faster of course but probably 
little effect overall as this is not that often executed.

97775235ec Simplify/Optimize another of the mbaff loop filter cases. 
Its faster but too rarely used to make a differnce.

085d9d98e8 Only calculate the second chroma qp if it differs from the firstin the main 
loop filter. (a little faster for the common case where they are equal)

b6ef858ec7 Move CAVLC 8x8 DCT special case from ff_h264_filter_mb() to fill_caches 
that way it is also available for ff_h264_filter_mb_fast().

6d7e6b2657 Perform reference remapping at fill_cache() time instead of in the 
loop filter. This removes one obstacle of getting ff_h264_filter_mb_fast()
bitexact. code is maybe 0.1% faster

c988f97566 Rearchitecturing the stiched up goose part 1 
Run loop filter per row instead of per MB, this also should make it
much easier to switch to per frame filtering and also doing so in a
seperate thread in the future if some volunteer wants to try.
Overall decoding speedup of 1.7% (single thread on pentium dual / cathedral sample)
This change also allows some optimizations to be tried that would not have
been possible before.

7931bb2a0c Comment for() ; out 
~200 bytes smaller ff_h264_filter_mb()
please everyone, NEVER add code with the assumtation that gcc will remove it
without checking gcc actually does. Chances are it does not.

ed3d7e2f65 Mark a few functions as noinline, this makes ff_h264_filter_mb() a bit smaller 
and 5% faster.
ff_h264_filter_mb_fast() stay the same size as gcc decided not to inline these
functions there in the first place.
