    * lto-streamer-out.c (DFS::worklist): New struct.
    (DFS::worklist_vec): New data member.
    (DFS::next_dfs_num): Remove.
    (DFS::DFS): Rewritten using worklist instead of recursion,
    using most of code from DFS::DFS_write_tree.
    (DFS::DFS_write_tree_body): Remove SINGLE_P argument, don't
    pass it to DFS_write_tree calls.
    (DFS::DFS_write_tree): Remove SINGLE_P argument, after
    quick initial checks push it into worklist_vec and return.
