I asked Microsoft about these records, and it turns out that they are completely unused for debugging. They only exist to power link-time devirtualization. In fact, they are never included in the final linked PDB.

So, I'm going to revert most of this patch, and do something more minimal to get the VFPtr records in the field list.
