[SPARK-16174][SQL] Improve `OptimizeIn` optimizer to remove literal repetitions

## What changes were proposed in this pull request?

This PR improves `OptimizeIn` optimizer to remove the literal repetitions from SQL `IN` predicates. This optimizer prevents user mistakes and also can optimize some queries like [TPCDS-36](https://github.com/apache/spark/blob/master/sql/core/src/test/resources/tpcds/q36.sql#L19).

**Before**
```scala
scala> sql("select state from (select explode(array('CA','TN')) state) where state in ('TN','TN','TN','TN','TN','TN','TN')").explain
== Physical Plan ==
*Filter state#6 IN (TN,TN,TN,TN,TN,TN,TN)
+- Generate explode([CA,TN]), false, false, [state#6]
   +- Scan OneRowRelation[]
```

**After**
```scala
scala> sql("select state from (select explode(array('CA','TN')) state) where state in ('TN','TN','TN','TN','TN','TN','TN')").explain
== Physical Plan ==
*Filter state#6 IN (TN)
+- Generate explode([CA,TN]), false, false, [state#6]
   +- Scan OneRowRelation[]
```

## How was this patch tested?

Pass the Jenkins tests (including a new testcase).
