    c++: templated static local var has value-dep addr [PR98930]

    Here uses_template_parms returns false for the dependent type A<&impl::i>,
    which causes tsubst_aggr_type to think it's non-dependent and not bother
    substituting into it, leading to breakage.

    This patch fixes this by making has_value_dependent_address also return
    true for templated static local variables.

            PR c++/98930

    gcc/cp/ChangeLog:

            * pt.c (has_value_dependent_address): Return true for a static
            local variable from a function template.

    gcc/testsuite/ChangeLog:

            * g++.dg/cpp1z/nontype4.C: New test.
            * g++.dg/cpp1z/nontype4a.C: New test.
