* doc/invoke.texi: Document -mtune, delete -mcpu

        option for S/390 and zSeries.
        * config/s390/s390.c (s390_tune_string) New variable.
        (s390_cpu_string) Delete variable.
        (override_options): Use s390_tune_string instead of
        s390_cpu_string.
        * config/s390/s390.h: (TARGET_OPTIONS) '-mtune' instead of '-mcpu'.
