Creates a new pointer that is dangling, but non-null and well-aligned.
This is useful for initializing types which lazily allocate, like `Vec::new`
does.
Note that the pointer value may potentially represent a valid pointer to a `T`,
which means this must not be used as a “not yet initialized” sentinel value.
Types that lazily allocate must track initialization by some other means.
