[Patch] cost function for S/390


This is another rtx_cost function fix for the IBM S/390.
The "multiply and add" case is now recognized in SFmode too.
Tested and bootstrapped without regressions on s390x.

        * config/s390/s390.c (struct processor_costs): Two new fields:
        madbr, maebr.
        (s390_rtx_costs): Added handling of multipy and add in SFmode.
        More precise values for cost of multiply and add.
