Derek Peschel bb9fa6f258 TX-0: Adjust CPU cry to reflected documented behavior and separated from pad
Before, when the simulator decoded pad, it handled pad without cry
and pad with cry. When it decoded cry, it printed a "TO DO" message.

http://bitsavers.org/pdf/mit/tx-0/memos/M-5001-19_macros_Apr60.pdf
derives a simple algorithm for cry. Implement that, remove the test
for cry from the pad code, and reformat the debug messages.

The same change appears in sim_instr and sim_opr_orig.
