DebugInfo: Reimplement DIRef<>::resolve() using TypedDebugNodeRef<>
Gut `DIRef<>::resolve()`, reimplementing it using
`TypedDebugNodeRef<>::resolve()`. Use three separate functions rather
than some sort of type traits, since the latter (i.e., mapping `DIScope`
=> `MDScope`) seems heavy-handed. I don't expect `DIRef<>` to last much
longer in tree anyway.
As a drive-by fix, make `TypedDebugNodeRef<>::resolve()` do the right
thing with `nullptr`.
