Meh.  To my mind, the most interesting aspects of different hardware
platforms for our purposes are

* alignment sensitivity (particularly, is unaligned access expensive);
* spinlock support, and after that various other atomic instructions;
* endianness

Pointer width is interesting, but really it's a solved problem
compared to these.
