    Evaluate condition arguments with the correct type.
    
    Processing of a cond_expr requires that a range of the correct type for the
    operands of the cond_expr is passed in.

            * gimple-range-gori.cc (gori_compute::condexpr_adjust): Use the
              type of the cond_expr operands being evaluted.
