Thus we do not need to provide specialist LD/ST "Structure Packed" opcodes
because the generic abstracted concept of "Remapping", when applied to
LD/ST, will give that same capability, with far more flexibility.
+It is worth noting that Pack/Unpack Modes of SVSTATE, which may be
+established through sv.setvl, are also an easy way to perform regular
+Structure Packing, at the vec2/vec3/vec4 granularity level. Beyond
+that, REMAP will need to be used.
