    c++: stream PACK_EXPANSION_EXTRA_ARGS [PR106761]

    It looks like after the libstdc++ commit r13-2158-g02f6b405f0e9dc
    some xtreme-header-* tests are failing with "conflicting global module
    declaration" errors ultimately because we're neglecting to stream
    PACK_EXPANSION_EXTRA_ARGS, which leads to wrong equivalences of
    different partial instantiations of _TupleConstraints::__constructible.

            PR c++/106761

    gcc/cp/ChangeLog:

            * module.cc (trees_out::type_node) <case TYPE_PACK_EXPANSION>:
            Stream PACK_EXPANSION_EXTRA_ARGS.
            (trees_in::tree_node) <case TYPE_PACK_EXPANSION>: Likewise.

    gcc/testsuite/ChangeLog:

            * g++.dg/modules/pr106761.h: New test.
            * g++.dg/modules/pr106761_a.H: New test.
            * g++.dg/modules/pr106761_b.C: New test.
