Frontend can emit errors when releaseing the Builder. If there are errors before or when releasing the Builder, we reset the module to stop here before invoking the backend. Before this commit, clang will continue to invoke the backend and backend can crash. Differential Revision: http://reviews.llvm.org/D16564 llvm-svn: 259116
