<pre>Currently, any field in the debug info hierarchy that can point at an
MDCompositeType returns `Metadata*`, since it could be an MDString or an
MDCompositeType.
We should port the DITypeRef/DIScopeRef/etc. wrappers over so that the factory
functions and accessors are more restrictive and clear.</pre>
