    openmp: Fix ICE on non-rectangular loop with known 0 iterations

    The loops in the testcase are non-rectangular and have 0 iterations
    (the outer loop iterates, but the inner one never).  In this case we
    just have the overall number of iterations computed (0), and don't have
    factor and other values computed.  We never need to map logical iterati=
ons
    to the individual iterations in that case, and we were crashing during
    expansion of that code.
