Replace ia64 S_UNLOCK compiler barrier with a full memory barrier.
Andres Freund <andres@anarazel.de>
Replace ia64 S_UNLOCK compiler barrier with a full memory barrier. _Asm_sched_fence() is just a compiler barrier, not a memory barrier. But spinlock release on IA64 needs, at the very least, release semantics. Use a full barrier instead. This might be the cause for the occasional failures on buildfarm member anole.
