[SPARK-16771][SQL] WITH clause should not fall into infinite loop.

## What changes were proposed in this pull request?

This PR changes the CTE resolving rule to use only **forward-declared** tables in order to prevent infinite loops. More specifically, new logic is like the following.

* Resolve CTEs in `WITH` clauses first before replacing the main SQL body.
* When resolving CTEs, only forward-declared CTEs or base tables are referenced.
  - Self-referencing is not allowed any more.
  - Cross-referencing is not allowed any more.

**Reported Error Scenarios**
```scala
scala> sql("WITH t AS (SELECT 1 FROM t) SELECT * FROM t")
java.lang.StackOverflowError
...
scala> sql("WITH t1 AS (SELECT * FROM t2), t2 AS (SELECT 2 FROM t1) SELECT * FROM t1, t2")
java.lang.StackOverflowError
...
```
Note that `t`, `t1`, and `t2` are not declared in database. Spark falls into infinite loops before resolving table names.

## How was this patch tested?

Pass the Jenkins tests with new two testcases.
