`fputil::cast` lacks specialization for targets that have fast half precision to single precision conversions. This leads to the cast being emulated when it could be done using the much faster `static_cast`. This was observed to cause a slow down, during the performance testing of the `hypotf16` function being introduced [here](https://github.com/llvm/llvm-project/pull/131991).
