[modules] When checking the include guard for a header, check whether it's visible in the module we're considering entering. Previously we assumed that if we knew the include guard for a modular header, we'd already parsed it, but that need not be the case if a header is present in the current module and one of its dependencies; the result of getting this wrong was that the current module's submodule for the header would end up empty. llvm-svn: 241953 2015-07-11 06:27:17 +08:00			`// RUN: rm -rf %t`
