emu: UNTESTED string ops, CMP instruction
...
Likely to be a bugfest.
There's a flags macro for now but unclear how useful it will turn out
to be in practice. Flags in particular need testing.
Also disappointing that I couldn't make instructions generic across
u8/u16, especially for ordinary, non-string CMP. Need to look into
this more to see if it can be done with num-traits or some other
trickery.

emu: wrap cpu regs in Cell. r16 addr mode.
...
r16 + modrm16 allowed cpu regs to alias. Wrap them in Cell to allow
this. We also create a Reg wrapper when passing regs so that we can
pass as &mut while simultaneously having other references to the same
reg.
