Change from last_opcode/last_operand to opcode/operand

Add addr_mode field, rely upon it vs. the opcode
...
This makes testing _slightly_ easier, because now the handlers require a
type of state in the cpu vs. a specific opcode state in the segment that
we execute from. (The latter being just more complex to work with and
require in testing.)
