* tree-ssa-loop-niter.c (idx_infer_loop_bounds): We can't get realistic
estimates here.
* tree-ssa-loop-unswitch.c (tree_unswitch_single_loop): Use also
max_loop_iterations_int.
(tree_unswitch_outer_loop): Likewise.
* tree-ssa-loop-ivopts.c (avg_loop_niter): Likewise.
* tree-vect-loop.c (vect_analyze_loop_2): Likewise.
