When SUBVL is greater than 1 a given group of Subvector
elements are kept together: effectively the group becomes the
-element, and the group is REMAPed together.
+element, and with REMAP applying to elements
+(not sub-elements) each group is REMAPed together.
Swizzle *can* however be applied to the same
instruction as REMAP, providing re-sequencing of
Subvector elements which REMAP cannot. Also as explained in [[sv/mv.swizzle]], [[sv/mv.vec]] and the [[svp64/appendix]], Pack and Unpack Mode bits
