op.c: Turn on read-only flag for folded constants

They are marked PADTMP, which causes them to be copied in any contexts
where readonliness makes a difference, so marking them as read-only
does not change the behaviour.  What it does is allow a future commit
to implement string swiping for PADTMPs.
