    c++: CTAD and member function references [PR103943]

    More quirks of rewriting member references to dependent references for
    CTAD.  A reference to a member of dependent scope is definitely depende=
nt.
    And since r11-7044, tsubst_baselink builds a SCOPE_REF, so
    tsubst_qualified_id should just use it.

            PR c++/103943

    gcc/cp/ChangeLog:

            * pt.cc (tsubst_qualified_id): Handle getting SCOPE_REF from
            tsubst_baselink.
            (instantiation_dependent_scope_ref_p): Check dependent_scope_p.

    gcc/testsuite/ChangeLog:

            * g++.dg/cpp1z/class-deduction109.C: New test.=
