basic structure packing on sub-elements. Bits 4-5 (normally elwidth) are
taken up as Pack/Unpack bits. Saturation may be simultaneously enabled.
-Note that ffirst and reduce modes are not anticipated to be high-performance in some implementations. ffirst due to interactions with VL, and reduce due to it requiring additional operations to produce a result. normal, saturate and pred-result are however inter-element independent and may easily be parallelised to give high performance, regardless of the value of VL.
