The returned value is currently unused. It also seems to imply that it somehow represents 'printf-style' the number of characters/bytes written to some output stream (which is incorrect, as we only know the actual size of the written message when we have rendered it, e.g. via GetString and DiagnosticManagers have no associated output stream). llvm-svn: 368577
