  Changed paths:
    M libcxx/include/__algorithm/iterator_operations.h
    A libcxx/test/libcxx/algorithms/bad_iterator_traits.verify.cpp

  Log Message:
  -----------
  [libc++] Make `_IterOps::__iter_move` more similar to `std::ranges::iter_move`.

Avoid relying on `iterator_traits` and instead deduce the return type of
dereferencing the iterator. Additionally, add a static check to reject
iterators with incorrect `iterator_traits` at compile time.
