Also it can have a pointer to a Bit8u, Bit16u, Bit32u and signed
equivalents and do the right thing.
- add lots more CPU fields as parameters: EBP ESI EDI ESP, all segment regs,
LDTR, GDTR, eflags, DR*, TR*, CR*. These are all visible on a
ridiculously tall dialog box that will one day become the debugger.
