Mike Reed ee655f8a94 Defensively reset aa[] value when we call a blitter repeatedly
The blitAntiH() entry point for blitters takes (sparse) arrays for
coverage (aa) and run lengths (runs). These are marked as "const", but
some blitter "helpers" like SkRgnClipBlitter modify their contents
in-place (to efficiently handle subsets of the runs).

This is normally fine, but if the caller is repeatedly using the same
buffers (as we do in call_hline_blitter, which has a finite sized
tmp buffer), we need to defensively reset the starter values each time
through the local loop.
