The following removes the optimization eliding the maybe_zero condition
from number_of_iterations_lt_to_ne when the IV can overflow since the
IV delta input is not accurately reflecting this.
PR tree-optimization/122537
* tree-ssa-loop-niter.cc (number_of_iterations_lt_to_ne): Register
may_be_zero condition when the IV may overflow.
* gcc.dg/torture/pr122537.c: New testcase.
