Compares the wrapped pointers of two propagate_consts, or between a propagate_const and nullptr, or between a propagate_const and another object.

1-4) Equality comparison for a propagate_const and nullptr.
5-6) Equality comparison for two propagate_consts
7-10) Ordered comparison for two propagate_consts
11-14) Equality comparison for a propagate_const and another object.
