This is a workaround and it would be better to fix this generally, but doing it generally is quite tricky. See D48541 and PR38117. Doing it in PredicateInfo directly allows us to use the type address to differentiate different unnamed types, because neither the created declarations nor the ssa_copy calls should be visible after PredicateInfo got destroyed.
