I am thinking hard about it, but that's an ugly hack to put into Clang.
It would be better if we could use "half" unconditionally and fptrunc/fpext instead of the conversion intrinsics, but that brings its own problems (like InstCombine folding things down to real, non-trivial operations on "half").
I'm still not quite sure what the best solution is or how much work would be involved in the different approaches.
Cheers.
Tim.
