In #99726, `-fptrauth-type-info-vtable-pointer-discrimination` was introduced, which is intended to enable type and address discrimination for type_info vtable pointers. However, some codegen logic for actually enabling address discrimination was missing. This patch addresses the issue. Fixes #101716
