PR target/31167
        * config/i386/i386.md (*addti3_1, *addti3_1 splitter): Use
        x86_64_general_operand as operand[2] predicate.  Remove "iF"
        from operand constraints and use "e" constraint instead.
        (*subti3_1, *subti3_1 splitter): Ditto.
        (*negti2_1, *negti2_1 splitter): Use nonimmediate_operand as
        operand[1] predicate.
