Right, that's what I meant, sorry.

Just to make sure we're on the same page...

If we treat this as an acceptable API change, we'll have to document.
This will force people to bootstrap Clang (if using pre-3.9 for stage
one), and only compile libunwind on stage 2.

If we try to fix, there should be some #ifdef clang < 3.9 #define
_URC_OK 0 #endif in the personality routine, or something similar.

Unless there's a better fix...
