(record_estimate): Only record constant upper bound. (infer_loop_bounds_from_undefined): Call compute_estimated_nb_iterations just once. (proved_non_wrapping_p): Renamed to ... (n_of_executions_at_most): ... this. Expect bound to be a constant. (convert_step_widening, scev_probably_wraps_p): Call n_of_executions_at_most instead of proved_non_wrapping_p. (substitute_in_loop_info): Do not replace values in bounds. * cfgloop.h (struct nb_iter_bound): Remove "additional" field. Update comments. * gcc.dg/tree-ssa/loop-16.c: New test.
