Michael Gottesman 650600aa2f [upstream-update] dexonsmith in an upstream commit realized he missed an ...

iterator/pointer comparison issue that yields undefined behavior. This updates
Swift for the landing of this change in swift-llvm/stable.

I am going to cherry-pick the given change into swift-llvm/stable since there is no
reason not to do this now and it will prevent more of these conversions from
creeping into the code base.

We really want to avoid as much undefined behavior as we possibly can.
