* tree-flow.h (tree_ssa_unswitch_loops): Return unsigned int.
(canonicalize_induction_variables): Likewise.
(tree_unroll_loops_completely): Likewise.
(tree_ssa_prefetch_arrays): 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.
* tree-ssa-loop-ivcanon.c (canonicalize_induction_variables):
Likewise.
(tree_unroll_loops_completely): Likewise.
(remove_empty_loops): 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_complete_unroll): Use the return value of
tree_unroll_loops_completely.
(tree_ssa_loop_prefetch): Use the return value of
tree_ssa_prefetch_arrays.
* passes.c (execute_todo): Before Cleanup CFG, set
updating_used_alone and after cleanup CFG, call
recalculate_used_alone.
