        * tree-flow.h (tree_ssa_unswitch_loops): Return unsigned int.
        (canonicalize_induction_variables): Likewise.
        (tree_unroll_loops_completely): Likewise.

        (remove_empty_loops): Likewise.
        * tree-ssa-loop-unswitch.c (tree_ssa_unswitch_loops): Return
        TODO_cleanup_cfg instead of directly calling
        cleanup_tree_cfg_loop.

        Likewise.

        * tree-ssa-loop-prefetch.c (tree_ssa_prefetch_arrays): Likewise.
        * tree-ssa-loop.c (tree_ssa_loop_unswitch): Use the return value
        of tree_ssa_unswitch_loops.
        (tree_ssa_loop_ivcanon): Use the return value of
        canonicalize_induction_variables.
        (tree_ssa_empty_loop): Use the return value of
        remove_empty_loops.

        tree_ssa_prefetch_arrays.
        * passes.c (execute_todo): Before Cleanup CFG, set
        updating_used_alone and after cleanup CFG, call
        recalculate_used_alone.
