Without the pointer-tbaa changes (which is new on by default in Clang 20), we would always generate `any pointer`. Without this fix, we will generate different tags for different `void` pointer depths. 

With this fix, we will generate `any pointer` again for `void` pointers. I think this should be very safe to take.
