// If we have an enum, it will be promoted to an unsigned integer.
// But both types are unsigned, and have same bitwidth.
// So we should not emit any sanitization. Also, for inc/dec we currently assume
// (assert) that we will only have cases where at least one of the types
// is signed, which isn't the case here.
