Revert "inline common modecolorfilters"

This reverts commit c8b6828d4f172f7b5735dbc5e26a33c53a54e94f.

Reason for revert: looks like this messed up colorcomposefilter_wacky and colorcomposefilter_alpha.  I suspect we're missing a swap_rb or two.

Original change's description:
> inline common modecolorfilters
> 
> *seems* like we won't trigger layout tests, since chrome only uses Src, SrcIn and Modulate.
