  Changed paths:
    M libcxx/src/debug.cpp
    M libcxx/test/std/strings/basic.string/string.iterators/iterators.pass.cpp

  Log Message:
  -----------
  Implement N3644 "Null Forward Pointers" in _LIBCPP_DEBUG mode.

This functionality is tested in std/containers/sequences/vector/iterators.pass.cpp
(and similarly for all containers, but vector is the only one to be tested that
uses debug iterators).
