'classof' is a funny method, which has an inverted meaning from what
you might expect. This is saying that any Decl with a kind of
"Field" or "ObjcIvar" is an instance or subclass of FieldDecl.
Because ObjcIvar is a subclass of FieldDecl, this method should
return true for it so that:
cast<FieldDecl>(some_objcivar)
succeeds.
