// TESTING virtual bool is_equal(memory_resource const &) const noexcept
//
// Concerns:
// A) 'memory_resource' provides a function 'is_equal' with the required
// signature.
// B) 'is_equal' is noexcept.
// C) 'do_is_equal' is called using the same arguments passed to 'is_equal'
// and the resulting value is returned.
// D) 'do_is_equal' is called on the LHS object and not the RHS object.
