Anders Carlsson d6f1518cc9 Fix another regression from the "skip vtable pointer initialization" 
optimization. Make sure to require a vtable when trying to get the address
of a VTT, otherwise we would never end up emitting the VTT.

Anders Carlsson 9bd7d16440 When emitting the destructor for a class with a vtable, if we can determine 
that the destructor body is trivial and that all member variables also have either
trivial destructors or trivial destructor bodies, we don't need to initialize the
vtable pointers since no virtual member functions will be called on the destructor.

Fixes PR9181.
