Currently, users get error messages about RTTI descriptor mangling with no useful source location. This addresses that. Another approach would be to disable C++ exceptions by default in the driver when using the Microsoft C++ ABI. However, this makes it impossible to parse system headers that use exception handling constructs. By delaying the error to IRgen, we can figure out if we actually need to emit code for this construct. Additionally, users who are only interested in building refactoring tools on Windows still get a correct AST without having to add flags. Finally, this is consistent with what we do for SEH. llvm-svn: 207999
