`__wrap_iter` is an internal libc++ class that is used as an iterator type when (for some reason) we don't want to use raw pointers as an iterator. It is the iterator type for `vector` and `string` (but not `array` - not sure why). If we used pointers, all the operations on the iterators would be constexpr. With this patch, the corresponding operations on `__wrap_iter` are constexpr as well.
We'll have to do this when http://www.open-std.org/jtc1/sc22/wg21/docs/lwg-active.html#2938 is adopted.
No tests, because all the interesting constructors of `__wrap_iter` are private, and only accessed through friend functions.
I have written tests (after making the appropriate ctors public) and they seem to work.
