    c++: nested lambda capture pack [PR119345]

    tsubst_stmt already registers a local capture proxy as a
    local_specialization of both an outer capture proxy and the captured
    variable; we also need to do that in add_extra_args.

            PR c++/119345

    gcc/cp/ChangeLog:

            * pt.cc (add_extra_args): Also register a specialization
            of the captured variable.

    gcc/testsuite/ChangeLog:

            * g++.dg/cpp2a/lambda-targ14.C: New test.
