/* Atomic functions: similar to pycore_atomic.h, but don't need
   to declare variables as atomic.

Py_ssize_t type:

* value = _Py_atomic_size_get(&var)
   * _Py_atomic_size_set(&var, value)

Use sequentially-consistent ordering (__ATOMIC_SEQ_CST memory order):
   enforce total ordering with all other atomic functions.
