    c++: static memfn from non-dependent base [PR101078]

    After my patch for PR91706, or before that with the qualified call,
    tsubst_baselink returned a BASELINK with BASELINK_BINFO indicating a ba=
se
of
    a still-dependent derived class.  We need to look up the relevant base
binfo
    in the substituted class.

            PR c++/101078
            PR c++/91706

    gcc/cp/ChangeLog:

            * pt.c (tsubst_baselink): Update binfos in non-dependent case.

    gcc/testsuite/ChangeLog:

            * g++.dg/template/access39.C: New test.=
