Adjust fix PR c++/68948

gcc/cp/ChangeLog:

        PR c++/68948
        * pt.c (tsubst_baselink): Don't diagnose an invalid constructor
        call here.
        * semantics.c (finish_call_expr): Don't assume a constructor
        call is dependent if only the "this" pointer is dependent.  When
        building a constructor call, always use a dummy object.
