**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.
```

{
    const ASTTablesInSelectQueryElement * node = select_query.join();
    if (!node)
        return;
    auto & table_join = const_cast<ASTTablesInSelectQueryElement *>(node)->table_join->as<ASTTableJoin &>();
    if (table_join.strictness == ASTTableJoin::Strictness::Unspecified &&
        table_join.kind != ASTTableJoin::Kind::Cross)
    {
        if (join_default_strictness == JoinStrictness::ANY)
            table_join.strictness = ASTTableJoin::Strictness::Any;
        else if (join_default_strictness == JoinStrictness::ALL)
            table_join.strictness = ASTTableJoin::Strictness::All;
        else
            throw Exception("Expected ANY or ALL in JOIN section, because setting (join_default_strictness) is empty",
                            DB::ErrorCodes::EXPECTED_ALL_OR_ANY);
    }
    if (old_any)
    {
        if (table_join.strictness == ASTTableJoin::Strictness::Any &&
            table_join.kind == ASTTableJoin::Kind::Inner)
        {
            table_join.strictness = ASTTableJoin::Strictness::Semi;
            table_join.kind = ASTTableJoin::Kind::Left;
        }
        if (table_join.strictness == ASTTableJoin::Strictness::Any)
            table_join.strictness = ASTTableJoin::Strictness::RightAny;
    }
