Currently, we cannot use `Float16.class` like we can `Integer.class` that describes the vector element type to the intrinsic. Could we use an internal class that acts as a proxy until we can replace it?

Hi @PaulSandoz , 
We will still need to create T_FLOAT16 basic type and associate it with Float16 LaneType, why not directly pass these basic types to intrinsic entry point ?
