       Base type for atomic_flag.

       Base type is POD with data, allowing atomic_flag to derive from it and meet the standard layout type
       requirement. In addition to compatibility with a C interface, this allows different implementations of
       atomic_flag to use the same atomic operation functions, via a standard conversion to the
       __atomic_flag_base argument.
