    s390: Deal with non-compare conditions during RTX costing [PR125972]

    During cprop we have to cost intermediate RTXs which may have
    non-compare conditions as e.g. r108={(0x1)?r113:r109} which get folded
    later on.

    First seen with r16-5417-g97a7d568f3d720.

            * config/s390/s390.cc (s390_rtx_costs): Deal with non-compare
            conditions during costing.  Also fix some indentation.

            * gcc.target/s390/pr125972.c: New test.
