URL: https://github.com/apache/doris/pull/22828

   ## Proposed changes
   
   ```
   drop TABLE if exists test1;
   
   CREATE TABLE test1 (
       dt1 date NOT NULL,
       dt2 date NOT NULL,
       id varchar(256) NULL,
       type smallint(6) MAX NULL,
       id_bitmap bitmap BITMAP_UNION NULL
   ) ENGINE = OLAP AGGREGATE KEY(dt1, dt2, id) PARTITION BY RANGE(dt1) (
       PARTITION p20230725
       VALUES
           [('2023-07-25'), ('2023-07-26')))
   DISTRIBUTED BY HASH(dt1, dt2) BUCKETS 1 properties("replication_num"="1");
   
   insert into test1
   select
   str_to_date('2023-07-25','%Y-%m-%d') as dt1,
   str_to_date('2023-07-25','%Y-%m-%d') as dt2,
   'aaaaaaaaaa' as id,
   1 as type,
   BITMAP_HASH64('aaaaaaaaaa') as id_bitmap;
   
   set experimental_enable_nereids_planner=false;
   set experimental_enable_pipeline_engine = true;
   select count(distinct id), 
bitmap_count(orthogonal_bitmap_intersect(id_bitmap, type, 1)) as count2_bitmap 
from test1; 
   ```
   
   Query will hang, because this sql contains two orthogonal_bitmap_intersect, 
this is not correct usage.
