    Fix division by zero in loop splitting

    Profile update I added to tree-ssa-loop-split can divide by zero in
    situation that the conditional is predicted with 0 probability which
    is triggered by jump threading update in the testcase.

    gcc/ChangeLog:

            PR middle-end/110923
            * tree-ssa-loop-split.cc (split_loop): Watch for division by zero.
