* config/s390/s390.md ("*fmadddf4", "*fmsubdf4", "*fmaddsf4",
"*fmsubsf4"): Insns are now dependent on TARGET_FUSED_MADD instead
of flag_unsafe_math_optimizations.
* config/s390/s390.h ("MASK_NO_FUSED_MADD", "TARGET_NO_FUSED_MADD",
"TARGET_FUSED_MADD", "TARGET_SWITCHES"): Introduced new target flags
fused-madd and no-fused-madd.
* doc/invoke.texi: Documented the new options fused-madd and
no-fused-madd for S/390.
