    Backport from mainline r176276
    2011-07-14  Georg-Johann Lay
    * config/avr/avr.md (rotl<mode>3): Generate SCRATCH instead
    of REG.
    (*rotw<mode>): Use const_int_operand for operand2.
    Use match_scatch for operand3.
    (*rotb<mode>): Ditto
    * config/avr/avr.c (avr_rotate_bytes): Treat SCRATCH.
