new c4c37a4 Rewritten subquery in having clause (#3206)
c4c37a4 is described below
commit c4c37a4394368a49704e374c0567a5d96c455205
Author: EmmyMiao87 <522274...@qq.com>

Rewritten subquery in having clause (#3206)
The subquery in having clause should be rewritten too.
If not, ExprRewriteRule will not be apply in subquery.
For example:
select k1, sum (k2) from table group by k1 having sum(k2) > (select t1 from
table2 where t2 between 1 and 2);
```t1 between 1 and 2``` should be rewritten to ```t1 >=1 and t1<=2```.
Fixed #3205. TPC-DS 14 will be passed after this commit.
