    c++: noexcept and pointer to member function type [PR113108]

    We ICE in nothrow_spec_p because it got a DEFERRED_NOEXCEPT.
    This DEFERRED_NOEXCEPT was created in implicitly_declare_fn
    when declaring

      Foo& operator=(Foo&&) = default;

    in the test.  The problem is that in resolve_overloaded_unification
    we call maybe_instantiate_noexcept before try_one_overload only in
    the TEMPLATE_ID_EXPR case.

            PR c++/113108

    gcc/cp/ChangeLog:

            * pt.cc (resolve_overloaded_unification): Call
            maybe_instantiate_noexcept.

    gcc/testsuite/ChangeLog:

            * g++.dg/cpp1z/noexcept-type28.C: New test.
