(I apologize in advance for not answering your question.) I always get uneasy when I see questions about when an instruction was *first* available. There's no assumption in Principles of Operation that once an instruction is introduced then it will be on all following machine. I know that in general it has worked that way in the past, but there's always a possibility that, say, an EC-type machine will introduce some new facility and then a later BC-type machine will be released without that facility. I don't know why you're asking the question, but would it be better answered by inspecting a facility bit stored by STFL(E)? If not, well, again I apologize.
