Add the new @llvm.nacl.atomic.fence.all intrinsic
This is a follow-up to:
https://codereview.chromium.org/22240002/
And requires the Clang changes from:
https://codereview.chromium.org/22294002/
This new intrinsic represents ``asm("":::"~{memory}")`` as well as ``__sync_synchronize()``, and in IR it corresponds to a sequentially-consistent fence surrounded by ``call void asm sideeffect "", "~{memory}"()``.
