This was removed upstream in https://reviews.llvm.org/D47789 since the only place this flag was used was in the windows implementation where the behavior triggered by this could be hidden in the implementation instead of being an argument. As such, this code doesn't compile on master-next. Since this has an acceptable default argument given the current stable, we can just fix this on master and everything will work. rdar://42862352
