Yes, but see: it's not the field itself that is being stored or read
readonly, it's the whole structure. Yet the structure is not
readonly.
Yes, that's what readonly_fields_p is all about: to handle precisely
that case.
I'd just decide that RTX_UNCHANGING_P is not the construct that should
be used to represent constant fields.
Then what is? We certainly want to indicate *somehow* that they can't
change.
