  Changed paths:
    M libcxx/test/std/utilities/format/format.formatter/format.parse.ctx/check_arg_id.pass.cpp
    M libcxx/test/std/utilities/format/format.formatter/format.parse.ctx/next_arg_id.pass.cpp

  Log Message:
  -----------
  [libc++] Guard testing implementation details.

The unit tests test some implementation details. As @Quuxplusone pointed
out in D96664 this should only be tested when the tests use libc++. This
addresses the issue for code already in main.
