Thinking about this more, I'm fine with either this patch or one that does not define `__libcpp_is_floating_point<_Float16>` at all. This patch provides the best level of support that we seem to be able to provide, but is inconsistent across compilers and does not follow the standard perfectly. Not providing the definition at all decreases the level of support but increases consistency and simplicity. I'm fine with either.
