92284aaa35 * mn10300_sim.h (_state): Add another register (MDR).
(REG_MDR): Define.
        * simops.c: Implement "cmp", "calls", "rets", "jmp" and
        a few additional random insns.
We can now function calls.  We get out of crt0 into main now, then lose
when calls are nested (because don't handle movm yet).

73e6529893 * mn10300_sim.h (PSW_*): Define for CC status tracking.
(REG_D0, REG_A0, REG_SP): Define.
        * simops.c: Implement "add", "addc" and a few other random
        instructions.
Starting to simulate instructions for the mn10300.  Executes some of
the crt0 code now!
