    I have a question about the validity of CLASSTYPE_VBASECLASSES.
Due to templates, it is not possible to know if a class has virtual
bases or not until the class is fully instantiated.  Is checking
processing_template_decl sufficient to guarantee that
CLASSTYPE_VBASECLASSES is valid?

No; if the class is presently being defined, that will not be set. However, it should be safe to check that for a complete class when !processing_template_decl.
