Commit 30d7ae3c76d2de144232ae6ab328ca86b70e72c3 introduced an HJDEBUG stanza that probably didn't compile at the time, and definitely doesn't compile now, because it refers to a nonexistent variable. It doesn't seem terribly useful anyway, so just get rid of it. While I'm fooling with it, use %z modifier instead of the obsolete hack of casting size_t to unsigned long, and include the HashJoinTable's address in each printout so that it's possible to distinguish the activities of multiple hashjoins occurring in one query. Noted while trying to use HJDEBUG to investigate bug #13908. Back-patch to 9.5, because code that doesn't compile is certainly not very helpful.
