This adds RzIL lifting for all legal 6502 ops, except the special bcd modes of adc and sbc for now. The lifting of every one of these ops is covered by an asm test, making sure all IL is valid. Some manual execution tests are available too, including one that runs a simple real-world xor-"decryption" loop. The lifting has not been tested against traces yet, so minor mistakes in the semantics are currently expected.
