7a6c7067f0 target-s390: Tidy s->op_cc handling 
There's no need to force computation of the true cc_op when taking an
exception or single stepping.  In either case we'll enter the next TB
with s->cc_op = DYNAMIC and recompute anyway.  Just make sure that
s->cc_op is stored back to env->cc_op as needed.

Delete some dead functions, avoid allocating unused TCG temps, drop
the old s->is_jmp setting.

4f3adfb2a6 target-s390: Delete dead code from old translator 
The use of inline restricts detection of static functions that are
no longer used.  Limit the use of inline to those functions that
are conditionally used based on CONFIG_USER_ONLY.
