This option implicitly imports the Clang module with the same name as the module being built into every source file in the module being built. This will be used for mixed-source framework targets to give Swift code the same implicit visibility for Objective-C decls in the same module that it already has for other Swift decls. <rdar://problem/16701230> Swift SVN r17053
