Just in case anyone cares, the relevant vector types for alpha are:
v8i8, v4i16, and maybe v2i32 (only one unpack operation produces this
and one pack operations consumes it). Of course all the operations that
exist are (s|u)(min|max), packing, unpacking, and comparison. Not that
I am too worried about support.
