This makes sure we are printing more than one level of C++ template specializations when emitting a Swift struct name. For instance, `std::__wrap_iter<char*>` and `std::__wrap_iter<const char*>` are currently imported with the same name in Swift. This means the mangled string will be the same for these specializations, despite them being distinct types. This causes mangling errors. rdar://117485399
