  Changed paths:
    M libcxx/include/algorithm
    M libcxx/include/iterator
    A libcxx/test/std/iterators/iterator.primitives/iterator.operations/robust_against_adl.pass.cpp

  Log Message:
  -----------
  [libc++] ADL-proof <iterator>. `__convert_to_integral` is not a customization point.

The interesting change here is that we no longer consider `__convert_to_integral`
an ADL customization point for the user's types. I think the new behavior
is defensible. The old behavior had come from D7449, where Marshall explicitly
said "people can't define their own [`__convert_to_integral` overloads]."
