* 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.

Likewise.

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