Traditional Vector ISAs have vastly more (and more complex) addressing
modes: unit strided, element strided, Indexed, Structure Packing. All
of these had to be jammed in on top of existing Scalar instructions

"cheat" was therefore needed. The Immediate (D) is in some Modes
multiplied by the element index, which gives us element-strided.
For unit-strided the width of the operation (`ld`, 8 byte) is
