Love it. This will help optimise these more too. We can currently get into places where we can't prove only the bottom bits of a returned value are demanded so can't remove unnecessary vmovs. Test look good too from my understanding of how fp16 calling should work.

I unfortunately can't really claim to be an expert on calling conventions code or if these new functions are needed. Hopefully someone I added can take a look, and if not I can always go find out how it works.
