yes, but Im not sure I'm going to be able to gimple atomic in for
4.8... Im trying to make sure the C11 stuff gets in then its back to
gimple atomic... you never know tho... I'm just concerned about
introducing it that late in the cycle... I'll reconsider the plan in
the next week or two.. maybe I can get gimple atomic in first then the
C11 stuff... put on a mega-push in august...
