Aligned data is always best, Misaligned data comes at very low cost.
SW overhead = 0

Thinking about this for a bit... for a clean-sheet architecture
like My66000, could there actually be an advantage to do
struct layout like the VAX did, with everything aligned on byte
boundaries?  On the plus side, there would be lower memory use.
On the minus side... very low cost, as you wrote above.
