Ensure that we delete destructors in the right cases. Specifically:
- variant members with nontrivial destructors make the containing class's
destructor deleted
- check for a virtual destructor after checking for overridden methods in the
base class(es)
- check for an inaccessible operator delete for a class with a virtual
destructor.
Do not try to call an anonymous union field's destructor from the destructor of
the containing class.
