    lwlock: Remove ForEachLWLockHeldByMe
    
    As of commit fcb9c977aa5, ForEachLWLockHeldByMe(), introduced in f4ece891fc2f,
    is not used anymore, as content locks are now implemented in bufmgr.c.  It
    doesn't seem that likely that a new user of the functionality will appear all
    that soon, making removal of the function seem like the most sensible path. It
    can easily be added back if necessary.
