fold-const.c (fold): Move bit_rotate code to the EXPR_PLUS case, falltrought to assocate code.

        * fold-const.c (fold): Move bit_rotate code to the EXPR_PLUS case,
        falltrought to assocate code.
        Convert XOR to OR in code like (a&c1)^(a&c2) where c1 and c2 don't have
        bits in common.

        * combine.c (simplify_logical): Convert XOR to IOR if operands have
        no bits in common; remove XOR to ROTATE conversion.
