Report warnings and errors through events instead of printing directly the to the debugger's error stream. By using events, IDEs such as Xcode can report these issues in the UI instead of having them show up in the debugger console. The new diagnostic events are handled by the default event loop. If a diagnostic is reported while nobody is listening for the new event types, it is printed directly to the debugger's error stream. Differential revision: https://reviews.llvm.org/D121511
