Simple H/V loopfilter for VP8 in MMX, MMX2 and SSE2 (yay for yasm macros). Originally committed as revision 24029 to svn://svn.ffmpeg.org/ffmpeg/trunk

; macro called with 7 mm register indexes as argument, and 4 regular registers

; first 4 mm registers will carry the transposed pixel data
; the other three are scratchspace (one would be sufficient, but this allows
; for more spreading/pipelining and thus faster execution on OOE CPUs)
