I am wondering if this can be added to the base class _LocalMirrorImpl so that
we don't have to keep repeating it every time we do this lazy setting up of
name.

Not all mirrors have a simpleName. If we go with aggregating the natives, we
could move it to the DeclarationMirrorImpl, but currently no such beast exists.

Ok when you add that class move this into that class.
