struct Padded { char x; int y; };
[modules] Fix incorrect diagnostic mapping computation when a module changes 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 2018-02-09 09:15:13 +08:00			`#define pragma _Pragma("clang diagnostic push") _Pragma("clang diagnostic error \"-Wpadded\"") _Pragma("clang diagnostic pop")`
