Chris Lattner c88a23e8d7 Fix the rest of rdar://6243860 hopefully. This requires changing FileIDInfo ... to whether the fileid is a 'extern c system header' in addition to whether it is a system header, most of this is spreading plumbing around. Once we have that, PPLexerChange bases its "file enter/exit" notifications to PPCallbacks to base the system header state on FileIDInfo instead of HeaderSearch. Finally, in Preprocessor::HandleIncludeDirective, mirror logic in GCC: the system headerness of a file being entered can be set due to the #includer or the #includee. llvm-svn: 56688		2008-09-26 20:12:23 +00:00
