JDK-8267332 adds an optimization that adds boundaries for XOR results in XorI/LNode::Value, but that optimization take precedence over the constant folding path in AddNode::Value.

I (liach) think the problem traces back to JDK-8261008 which adds Xor optimization as XorI/LNode::Value instead of XorI/LNode::add_ring. The override to ::Value should be removed and all optimizations should happen in add_ring.
