Fix initial diagnostic state setup for an explicit module with no diagnostic pragmas. If a file has no diagnostic pragmas, we build its diagnostic state lazily, but in this case we never set up the root state to be the diagnostic state in which the module was originally built, so the diagnostic flags for files in the module with no diagnostic pragmas were incorrectly based on the user of the module rather than the diagnostic state when the module was built. llvm-svn: 301846

clang/test/Modules/diag-flags.cpp: Appease targeting *-win32 with explicit triple. Fixes r301846. MicrosoftRecordLayoutBuilder doesn't have ability of -Wpadded. FIXME: Would other diag be available here? llvm-svn: 301898
