No Alloc constant folding when no clients

This is because either: - There will never be any client and thus the node will be pruned, so performing constant folding would be a waste of time, or - Someone will add clients later and will re-run the constant folding phase, in which case we will want to use the client-dependent logic to decide whether constant folding should be applied or not.
