The more interesting question is the usage of Constant;  I think we can safely assume the integer component is always going to be a ConstantInt (because it's going to have to fit in a ConstantInt-shaped hole in CPA anyway.)  That hopefully makes this obvious here, and I'll propagate that in the various users separately
