50a84b4099 Remove cycles field from mos6502 struct 
It was both unused and not necessary, as we can simply compute the
number of cycles in the execute function.

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.

eaaf63a069 Zero out last_addr and cycles 
This fixes a super-annoying bug in the unit-test suite where we would
fail randomly because sometimes last_addr would have garbage in it.
