the global binding is not working when using Prepared Statement with "select ... cast(.. as ..) from..."

## Bug Report

Please answer these questions before submitting your issue. Thanks!

### 1. Minimal reproduce step (Required)
CREATE TABLE t(id varchar(10) DEFAULT NULL,name varchar(10) DEFAULT NULL,KEY idx_id(id));
CREATE TABLE t1(id int DEFAULT NULL,name varchar(10) DEFAULT NULL,KEY idx_id(id));
explain analyze select * from t where id in(select cast(t1.id as char) id from t1);

create global binding for select * from t where id in(select cast(t1.id as char) id from t1) using select * from t where id in(select cast(t1.id as char) id from t1 use index());
prepare mystmt from "explain analyze select * from t where id in(select cast(t1.id as char) id from t1)";
execute mystmt;
