New 'blitAntiRect' entry point for blitters, specialized in supersampling
code to avoid quarter-scanline-at-a-time building of large rectangular
clips.

Speeds up aa_clip_build_path_AA benchmark 2x, aa_clip_build_rect_AA benchmark
10x or more. This is a sufficient performance gain to let Chromium reenable
WebKit's soft clipping code. Rolling into Chromium will require ~18
rebaselines.
