* m68k/m68k.c (m68k_last_compare_had_fp_operands): New variable.
        * m68k/m68k.h (m68k_last_compare_had_fp_operands): Declare it.
        * m68k/m68k.md (tst*, cmp*): Turn all of these into
        define_expand/define_insn pairs.  Keep track of whether or not
        the test/compare has fp operands.
        (seq, sne, sgt, slt, sge, sle): Turn these into
        define_expand/define_insn pairs.  Make the expanders FAIL if
        TARGET_68060 and the last comparison/test had fp operands.
