epiphany.c (epiphany_override_options): If TARGET_SOFT_CMPSF is not enabled, set flag_finite_math_only. 

gcc:
        * config/epiphany/epiphany.c (epiphany_override_options):
        If TARGET_SOFT_CMPSF is not enabled, set flag_finite_math_only.
        * config/epiphany/epiphany.md (mov<mode>cc): Don't use
        reverse_condition_maybe_unordered if flag_finite_math_only is set.
gcc/testsuite:
        * gcc.target/epiphany/fcmp-1.c: New test.
