* mn10300/mn10300.c (notice_update_cc): Enable this code.
* mn10300/mn10300.h (CC_OVERFLOW_UNUSABLE): Define.
* mn10300/mn10300.md (tstsi): Use "set_zn_c0" instead of "set"
for cc status.
(addsi3 pattern): Break "inc" into two different alternatives
since "inc dn" sets cc0, but "inc an" does not.
(multiply and divide patterns): Fix cc status.
(bCC, inverted bCC): Restore any comparison which needs the
overflow bits when CC_OVERFLOW_UNUSABLE is set.
(zero and sign extensions): Fix cc status.
(movm_store): Likewise.
