[libc++] Introduce __is_pointer_in_range

This checks whether a pointer is within a range, even during constant evaluation. This allows running optimized code paths during constant evaluation, instead of falling back to the general-purpose implementation all the time. This is also a central place for comparing unrelated pointers, which is technically UB.
