    tree-optimization/108793 - niter compute type mismatch

    When computing the number of iterations until wrap types are mixed up,
    eventually leading to checking ICEs with a pointer bitwise inversion.
    The following uses niter_type for the calculation.

            PR tree-optimization/108793
            * tree-ssa-loop-niter.cc (number_of_iterations_until_wrap):
            Use convert operands to niter_type when computing num.

            * gcc.dg/torture/pr108793.c: New testcase.=
