Returns a pointer to amemory_resource that doesn't perform any allocation.
Returns a pointerp to a static storage duration object of a type derived fromstd::experimental::pmr::memory_resource, with the following properties:
allocate() function always throwsstd::bad_alloc;deallocate() function has no effect;memory_resourcer,p->is_equal(r) returns&r == p.The same value is returned every time this function is called.
