My recollection is that I deliberately used LP_DELETE for the
known-dead-tuple marker so that there couldn't be any confusion with
the use of LP_USED.  AFAIR, LP_USED isn't actually used in indexes,
so we could do it differently if there were another possible use for
the flag bit ... have you got one in mind?
