This really belongs in the VMMaker inbox, but we don't have one of those so I uploaded it to SqS/VMMaker. If it causes problems, I appreciate if someone can do an update from VMMaker-dtl.172 and make this VMMaker-dtl.173 a branch. I may be out of town for a few days, so don't ask my permission. The purpose of this change is to move all of the BytesPerWord dependent stuff out to compile-time macros, enabling a single generated code base to produce VMs for either 32-bit or 64-bit image formats.
