Summary: Make this interface reusable similarly to std::call_once and std::once_flag interface. This makes porting LLDB to NetBSD easier as there was in the original approach a portable way to specify a non-static once_flag. With this change translating std::once_flag to llvm::once_flag is mechanical.
