[Mesa-dev] [PATCH 2/2] draw: allow overflows in the llvm paths

[Zack Rusin]

Because our code couldn't handle it we were skipping rendering
if we detected overflows. According to the spec we should
still render but with all 0 vertices, which is what the llvm
code already does. So for the llvm paths lets enable processing
even if an overflow condition has been detected.
