* tree-ssa-loop-niter.c (derive_constant_upper_bound): New function.
(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.
