[PATCH] Add AtomicExpandPass::bracketInstWithFences, and use it whenever getInsertFencesForAtomic would trigger in SelectionDAGBuilder

[Robin Morisset]

Cleanup of some now redundant code that I had missed.

I would love getting some reviews on this patch, other patches depend on it
(D5180 being one that is otherwise ready to land). Thanks !
