[SystemZ] Bugfix: check CC reg liveness in SystemZShortenInst.
The following instruction shortening transformations would introduce a
definition of the CC reg, so therefore liveness of CC reg must be checked:
WFADB -> ADBR
WFSDB -> SDBR
Also add the CC reg implicit def operand to the MI in case of change of opcode.
