    c++: Stream virtual dtor vtable indices

    Virtual cloned functions have distinct vtable indices, stream them
    explicitly.

    As such, this patch ensures that DECL_VINDEX is properly passed on for
    cloned functions as well to prevent this from causing issues.

            PR c++/103499

    gcc/cp/ChangeLog:

            * module.cc (trees_out::decl_node): Write DECL_VINDEX for
            virtual clones.
            (trees_in::tree_node): Read DECL_VINDEX for virtual clones.

    gcc/testsuite/ChangeLog:

            * g++.dg/modules/pr103499_a.C: New test.
            * g++.dg/modules/pr103499_b.C: New test.
