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.
