  1. [PAC] Fix address discrimination for type info vtable pointers 

    In llvm#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 llvm#101716
