FP16 in the ARM backend was a bit of work-in-progress around that time, it had some rough edges, and you're hitting one of them. But we have fixed a lot of them recently, and so it is in a good state now, that's why my top of trunk build works. As workarounds, which I realise might not be ideal, but you can try using a trunk build, or wait for clang-9 (or avoid this intrinsic if the rest works for you).
