is that it engages a swap of the ordering of the VL-SUBVL
nested for-loops, in exactly the same way that Matrix REMAP
can do. When Pack or Unpack is enabled it is the SUBVL for-loop

+Perhaps unsurprisingly the Scalar Power ISA does not have
+a Scalar GPR Move instruction: instead, there are a series

+and many more.

+Strictly speaking these may orthogonally be Vectorised and achieve
+the same effect as a Vector Move.
