**Usage**
Postgres, MySQL, and Oracle support the expression `LEFT JOIN ... ON 1 = 1`, but ClickHouse does not.

It may be possible to replace `LEFT JOIN ... ON 1 = 1` with `CROSS JOIN`, but I want to use the query in the same form for lots of databases.

Please support the expression `LEFT JOIN ... ON 1 = 1`.


**Detailed SQL**
```SQL
CREATE TABLE test
(
    `name` Nullable(String),
    `id` int
)
ENGINE = Log();

insert into test values ('a', 1) ('b', 2) (null, 3);

select * from test t1 left join (select * from test ) t2 on 1 = 1   
-- DB::Exception: Not equi-join ON expression: 1 = 1. No columns in one of equality side.: While processing 1 = 1.
```

{
        auto prefix = name.substr(0, name.size() - customized_func_suffix.size());
        auto prefix_size = prefix.size();
        if (endsWith(prefix, "MergeState"))
            return prefix.substr(0, prefix_size - 10) + customized_func_suffix + "MergeState";
        if (endsWith(prefix, "Merge"))
            return prefix.substr(0, prefix_size - 5) + customized_func_suffix + "Merge";
        if (endsWith(prefix, "State"))
            return prefix.substr(0, prefix_size - 5) + customized_func_suffix + "State";
        if (endsWith(prefix, "If"))
            return prefix.substr(0, prefix_size - 2) + customized_func_suffix + "If";
        return name;
    }
