PR tree-optimization/25985
* tree-ssa-loop-niter.c (number_of_iterations_le,
number_of_iterations_ne): Make comments more precise.
(number_of_iterations_cond): Add only_exit argument. Use the
fact that signed variables do not overflow only when only_exit
is true.
(loop_only_exit_p): New.
(number_of_iterations_exit): Pass result of loop_only_exit_p to
number_of_iterations_cond.
