i386.md (type attribute): Add "rotate" for rotate insns. 

        * i386.md (type attribute): Add "rotate" for rotate insns.
        (rotate insns): Set type to "rotate".
        (various attributes and function units): Treat rotate like shift.
        (pent_pair attribute): Only rotates by one bit position are
        pairable.
        (sbb insns): Explicitly set pent_pair attribute on a couple
        that were missing it.
