    c++: variable template array of unknown bound [PR113638]

    When we added variable templates, we didn't extend the
VAR_HAD_UNKNOWN_BOUND
    handling for class template static data members to handle them as well.

            PR c++/113638

    gcc/cp/ChangeLog:

            * cp-tree.h: Adjust comment.
            * pt.cc (instantiate_template): Set VAR_HAD_UNKNOWN_BOUND for
            variable template.

    gcc/testsuite/ChangeLog:

            * g++.dg/cpp1y/var-templ-array1.C: New test.
