Subject: rtx_cost function for S/390

This is yet another rtx_cost function fix for the IBM S/390.
Divide instructions are handled with more precision now.
Tested and bootstrapped without new regressions on s390x.

        * config/s390/s390.c (struct processor_costs): 4 new fields:
        ddbr, ddr, debr, der.
        (s390_rtx_costs): More precise handling of divide instructions.
