It isn't at all obvious that is_int_type() return false for
restricted/bitwise types. It's even quite counter-intuitive.
So document this.
Note: Fortunately, there isn't a lot of callers and the main
callers are all in parse.c and are OK. OTOH, the callers
in sparse-llvm.c are wrong and need another helper.
