c20fec4055 target-s390: Use TCG_CALL_NO_WG for integer helpers 
The division routines do not read or write tcg registers,
but can raise fixed-point divide exceptions.

bacf43c62e target-s390: Optimize get_address 
Don't load the displacement into a register first, add it second
so that tcg_gen_addi_i64 can eliminate zeros.  Don't mask the
displacement first so that we don't turn small negative numbers
into large positive numbers.

c95ec459c6 target-s390: Optimize ADDC/SUBB 
Giving the proper mask to disas_jcc allows us to generate an inline
comparison generating the carry/borrow with setcond.

In the very worst case, when we must use the external helper to compute
a value for CC, we generate (cc > 1) instead of (cc >> 1), which is only
very slightly slower on common cpus.

In the very best case, when the CC comes from a COMPARE insn and the
compiler is using ALCG with zero, everything folds out to become just
the setcond that the compiler wanted.

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.

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.
