    BZ #15536: Fix ulp for 128-bit IBM long double.

    In 128-bit IBM long double the precision of the type
    decreases as you approach subnormal numbers, equaling
    that of a double for subnormal numbers. Therefore
    adjust the computation in ulp to use 2^(MIN_EXP - MANT_DIG)
    which is correct for FP_SUBNORMAL for all types.
