operator<=> not defined for __wrap_iter

[ojrosten]

While it is possible to use three way comparison for iterators coming from e.g. std::array, this does not work for e.g. std::vector.

The culprit appears to be that oeprator<=> is not defined for the iterator wrapper used in the latter.

FYI This actually is not a bug, it was a feature we had not implemented yet. I just put up a patch for review.
