diagnostic settings using _Pragma within a macro. The AST writer had previously been assuming that all diagnostic state transitions would occur within a FileID corresponding to a file. When a diagnostic state change occured within a macro, it was unable to form a location for that state change and would instead corrupt the diagnostic state of the "root" node (and thus that of the main compilation). Also introduce a "#pragma clang __debug diag_mapping" debugging utility that I added to track this issue down. llvm-svn: 324695
