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.

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.

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.
