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.

target-s390: Convert ADD LOGICAL CARRY and SUBTRACT LOGICAL BORROW
...
I'm resonably certain that the carry/borrow-out condition for both
helpers was incorrect, failing to take into account the carry-in.
Adding the new CC_OP codes also allows removing the awkward interface
we used for the slb helpers.

Use a new "retxl" member of CPUS290XState to return the "eXtra Low" part
of a 128-bit value. That said, this will get used when two independent
values need returning (e.g. quotient+remainder) as well.
At the same time, shuffle the elements of CPUS390XState to get this new
space from existing padding in the structure.
