  GlobalISel: Translate llvm.convert.{to|from}.fp16 intrinsics

I think these were added as a workaround for SelectionDAG lacking half
legalization support in the past. I think they should probably be
removed from the IR, but clang does still have a target control to
emit these instead of the native half fpext/fptrunc.
