    rtl-optimization/118298 - constant iteration loops and #pragma unroll

    When the RTL unroller handles constant iteration loops it bails out
    prematurely when heuristics wouldn't apply any unrolling before
    checking #pragma unroll.

            loop->unroll even if the loop is too big for heuristics.
