c++: Member fns and deduction guide rewriting [PR98929]
My patch for 96199 had us re-substitute the parameter types of a constructor
in order to rewrite mentions of members into dependent references. We need
to do that for member functions, too.
gcc/cp/ChangeLog:

* error.c (dump_expr): Ignore dummy object.
* pt.c (tsubst_baselink): Handle dependent scope.

* g++.dg/cpp1z/class-deduction-decltype1.C: New test.
