    c++: Export usings referring to global module fragment [PR109679]

    This patch stops 'add_binding_entity' from ignoring all names in the
    global module fragment, since they should still be exported if named
    in an exported using-declaration.

            PR c++/109679

    gcc/cp/ChangeLog:

            * module.cc (depset::hash::add_binding_entity): Don't skip names
            in the GMF if they've been exported with a using declaration.

    gcc/testsuite/ChangeLog:

            * g++.dg/modules/using-11.h: New test.
            * g++.dg/modules/using-11_a.C: New test.
            * g++.dg/modules/using-11_b.C: New test.
