ART: Remove old aget on null workaround

Use null for an aget-object of null. Ensure that other aget types
on null cannot be converted to or used as a reference type.

Let the verifier continue scanning after an aget on a null register,
to ensure that the dead code is type-safe.

Add test coverage for the new behavior.
