Mike Klein f815301b1a add GM for skbug.com/9331
Release and debug builds draw differently on my machine,
and if I tack #pragma clang optimize off onto cull_rect()
in SkDashPath.cpp, they both draw like a debug build.

I'm not very familiar with this code, so it may help my
diagnosis to see what other bots draw.
