I tried to, but I don't know if I got everything right.  E.g. will
special registers grow as well?  What does loadaddr calculate when general
registers are wider than 64 bits?  Will loadconsx really sign-extend to
the full register size, or only to 64 bits?  Will `jmp r1, r2' ignore the
high part of r1, and will it clear or sign-extend the value put into r2?
Or maybe copy the remaining bits from r1?

Lots of questions.
