We were accidentally interning newly-added and newly-opened
non-root-visible types into name tables, and removing names from name
tables when such types were removed. This is very wrong: the whole
point of non-root-visible types is they do not go in name tables and
cannot be looked up by name. This bug made non-root-visible types
basically identical to root-visible types, right back to the earliest
days of libctf in the Solaris era.
