This needed two fixes:
* 32-bit instructions were read in the wrong order. The machine code
swaps the two 16-bit instruction words, which wasn't undone when
decoding instructions.
* Jump and call instructions don't encode the lowest address bit,
which is always zero. Therefore, the address needed to be shifted by
one to fix that.
