libctf: prohibit nameless ints, floats, typedefs and forwards
Now that "anonymous typedef nodes" have been extirpated, we can mandate
that things that have names in C must have names in CTF too. (Unlike
the no-forwards embarrassment, the deduplicator does nothing special
with names: types that have names in C will have the same name in CTF.
So we can assume that the CTF rules and the C rules are the same.)
