A value type like a struct or enum cannot conform to Copyable if it has a deinit. When NoncopyableGenerics is enabled, we make that part of what is required to verify that such a nominal type conforms to Copyable. This change also does some refactoring to share common code to point out how to make a type noncopyable.
