50a84b4099 Remove cycles field from mos6502 struct 
It was both unused and not necessary, as we can simply compute the

5ada987c83 Add the execute function for the 6502 
This executes a single opcode. Note this also makes a change to the
get_address_resolver function such that accepts an opcode, not the
address mode itself.
