Eric Fiselier 76a01ea34d Fix PR26961 - Add default constructor to std::pointer_safety struct.
In ABI v1 libc++ implements std::pointer_safety as a class type instead
of an enumeration. However this class type does not provide
a default constructor as it should. This patch adds that default constructor.
