fschneider@google.com 699add3afc VM: Make ZoneAllocated-objects that don't need a vtable smaller.
Remove virtual destructor from ZoneAllocated. Instead, subclasses
that need one have it explicitly declared.

This makes ZoneAllocated objects without virtual functions smaller
because there won't be a vtable for them.
