Until C++17 (inclusive), a default-constructed std::atomic object can, officially, only be initialized with a call to std::atomic_init, for which QBasicAtomic doesn't have API. It is even unclear whether zero-initialization of static and thread-local objects will cause the object to be initialized. To fix, port from QBasicAtomic to QAtomic (which initializes to zero).
