When writing a PCH file, keep track of all of the non-static, non-inline external definitions (and tentative definitions) that are found at the top level. The corresponding declarations are stored in a record in the PCH file, so that they can be provided to the ASTConsumer (via HandleTopLevelDecl) when the PCH file is read. llvm-svn: 69005 2009-04-14 00:24:19 +00:00			`// Helper for external-defs.c test`
