FWIW, I noticed that I needed one tweak to libc++/test/container/MoveOnly.h to
really make switching to __is_convertible_to useful: instead of declaring the
copy constructor and copy assignment operator as private, I declared them as
deleted (when deleted functions are available, which they are in Clang).
Or you could wait... I'm in the process of teaching __is_convertible_to to do
the right thing when there are access control failures, which will make the
MoveOnly.h tweak irrelevant.
