Predefined declarations (like _GUID) are special forward declarations inserted by Clang and aren't serialized into the pcm and their definition pointers aren't retained across serialization and deserialization, which causes this type not found error. Avoid putting non-defining predefined declarations into the swift lookup table when their definitions exist in the same module so that the definitions will be associated with the base name and avoid this error.
