Richard Henderson a359b770c6 target-s390: Optimize ADDU/SUBU CC testing 
We can easily generate some masks for logical add/subtract inline.

Richard Henderson de379661d5 target-s390: Tidy comparisons 
After full conversion, we can audit the uses of LTGT cc ops
and see that none of the instructions can ever set CC=3.
Thus we can extend the table to treat that bit as ignored.

This fixes a regression wrt the pre-conversion translation
in which NE was used for both m=6 and m=7.

Richard Henderson f24c49c24a target-s390: Optmize emitting discards 
While they aren't expensive, they aren't free to process.  When we
know that the three cc helper variables are dead, don't kill them.

Richard Henderson 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.

Richard Henderson 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.
