Antonio Sanchez abcde69a79 Disable vectorized pow for half/bfloat16.
We are potentially seeing some accuracy issues with these.  Ideally we
would hand off to `float`, but that's not trivial with the current
setup.

We may want to consider adding `ppow<Packet>` and `HasPow`, so
implementations can more easily specialize this.
