    [PR tree-optimization/107355] Handle NANs in abs range-op entry.

    The problem here is that the threader is coming up with a path where
    the only valid result is a NAN.  When the abs op1_range entry is
    trying to add the negative posibility, it attempts to get the bounds
    of the working range.  NANs don't have bounds so they need to be
    special cased.
