Streamline the factorial function; we don't need to save a stack variable
into a register before operating on it. All instructions can take a stack
variable directly.

In the process we found two bugs:

a) Opcode f7 was not implemented correctly. It was internally consistent
but I'd never validated it against a natively running program. Turns out
it encodes multiple instructions, not just 'not'.

b) The way we look up imm32 operands was sometimes reading them before
disp8/disp32 operands.
