> Hi all.
> `SubstitutionVisitor` support more join_type in some rules of `Join`.
> Now `SubstitutionVisitor` only support join type of `INNER`, when pulling up bottom filters of join.
> It doesn't work as follows. 
> {code:java}
> @Test public void testJoinOnLeftProjectWithFilterToJoin() {
>     String mv = ""
>         + "select \"emps\".\"empid\", \"depts\".\"name\", \"emps\".\"salary\"\n" +
>         "from \"emps\"\n" +
>         "left join \"depts\"\n" +
>         "on \"emps\".\"deptno\" = \"depts\".\"deptno\"\n"
>         + "where \"emps\".\"empid\" > 10";
>     String query = ""
>         + "select \"emps\".\"empid\", \"depts\".\"name\", \"emps\".\"salary\"\n" +
>         "from \"emps\"\n" +
>         "left join \"depts\"\n" +
>         "on \"emps\".\"deptno\" = \"depts\".\"deptno\"\n"
>         + "where \"emps\".\"empid\" > 40";
>     sql(mv, query).withOnlyBySubstitution(true).ok();
>   }
> {code}
