* m68k.c (const_uint32_operand): Abort if mode is <= 32 bits.
        (const_sint32_operand): Likewise.
        * m68k.md (anon mulsi pattern): Use const_int_operand not
        const_sint32_operand.
        (umulsi3_highpart): Zero extend a constant input.
        (smulsi3_highpart): Don't bother checking SImode constant.
        (const_umulsi3_highpart): Give op3 DImode.
        (const_smulsi3_highpart): Likewise.
