[PATCH] D53486: [libcxx] Only define __libcpp_is_floating_point<_Float16> for Clang

[Louis Dionne via Phabricator]

ldionne added a comment.

Question: @mclow.lists if `__fp16` supported all the proper operations required to be "a floating point type", would there be pushback against defining `is_floating_point` for `__fp16` as a library extension?
