Do not print inferred submodules explicitly in __inferred_module.map Otherwise including a header in your source file that is not included by framework's umbrella header will silently add an empty submodule with that name. is automatically translated to @import Foo.NotInModule; which then would have succeeded because the inferred module map contained an empty submodule called NotInModule. llvm-svn: 207024 2014-04-24 05:10:46 +08:00			`// RUN: rm -rf %t`
