Remove redundant PGPROC.lockGroupLeaderIdentifier field. We don't really need this field, because it's either zero or redundant with PGPROC.pid. The use of zero to mark "not a group leader" is not necessary since we can just as well test whether lockGroupLeader is NULL. This does not save very much, either as to code or data, but the simplification seems worthwhile anyway.
