This is the Objective-C version of a similar change to the Java
generaters, CL 34777.
This CL makes sure the types only implicitly referenced through method
parameters or return values are also reverse generated. In doing so,
the anonymous interface{} is never used by the reverse generator,
gaining type safety, removing a special case and making sure passing
values of implicit types can be passed across the language barrier.
To support implicit types, the Objective-C importer is changed to
extract the module of a type from the clang AST dump instead of
relying on the module implied by the Go reference (e.g.
ObjC/Foundation.NSString).
