tree-optimization/104519 - adjust PR100499 niter fix
The following adjusts the PR100499 niter fix to use the appropriate
types when checking whether the difference between the final and base
values of the IV are a multiple of the step. It also gets rid of
an always false condition in multiple_of_p which lead me to a
wrong solution first.
