<pre>The goal is to get correct VBPtrOffset values in the VirtualBaseClass type
records. My understanding is that all virtual bases should appear in the same
primary vbtable of the most derived class, so these offsets should all be the
same. That's why it makes sense to me to encode this as an artificial member,
instead of trying to augment DW_TAG_inheritance with an extra integer.</pre>
