check undefine_p for one more vr

The root cause of PR111355 and PR111482 is missing to check if vr0
is undefined_p before call vr0.lower_bound.

In the pattern "(X + C) / N",

    (if (INTEGRAL_TYPE_P (type)
	 && get_range_query (cfun)->range_of_expr (vr0, @0))
     (if (...)
       (plus (op @0 @2) { wide_int_to_tree (type, plus_op1 (c)); })
       (if (TYPE_UNSIGNED (type) && c.sign_mask () < 0 ...
	    && wi::geu_p (vr0.lower_bound (), -c))

In "(if (...)", there is code to prevent vr0's undefined_p,
But in the "else" part, vr0's undefined_p is not checked before
"wi::geu_p (vr0.lower_bound (), -c)".
