Ok.  We can extract it later and make it a separate module.  But there are
still some things to do, e.g. the opcode assignment needs to be redone
(I assigned them in no particular order; we definitely need to renumber
them if we want fast+easy instruction decoding inside the CPU).

Minor update: the relocation table is no longer missing :)

Not with the same program.  My encoder only gives you a one-way
ticket; there's no way to reverse the name -> code translation.
But it shouldn't be hard to write a disassembler module, too.

A full-blown simulator should contain a disassembler and a symbolic
debugger anyway :)
