…into a single batch.

SQL
```
select * from tableA join tableB on (a > 3 and b = d) or (a > 3 and b = e)
```
Plan before modify
```
== Optimized Logical Plan ==
Project [a#293,b#294,c#295,d#296,e#297]
 Join Inner, Some(((a#293 > 3) && ((b#294 = d#296) || (b#294 = e#297))))
  MetastoreRelation default, tablea, None
  MetastoreRelation default, tableb, None
```
Plan after modify
```
== Optimized Logical Plan ==
Project [a#293,b#294,c#295,d#296,e#297]
 Join Inner, Some(((b#294 = d#296) || (b#294 = e#297)))
  Filter (a#293 > 3)
   MetastoreRelation default, tablea, None
  MetastoreRelation default, tableb, None
```

CombineLimits ==> Limit(If(LessThan(ne, le), ne, le), grandChild) and LessThan is in BooleanSimplification ,  so CombineLimits  must before BooleanSimplification and BooleanSimplification must before PushPredicateThroughJoin.

…aggregations

## What changes were proposed in this pull request?
Partial aggregations are generated in `EnsureRequirements`, but the planner fails to
check if partial aggregation satisfies sort requirements.
For the following query:
```
val df2 = (0 to 1000).map(x => (x % 2, x.toString)).toDF("a", "b").createOrReplaceTempView("t2")
spark.sql("select max(b) from t2 group by a").explain(true)
```
Now, the SortAggregator won't insert Sort operator before partial aggregation, this will break sort-based partial aggregation.
```
== Physical Plan ==
SortAggregate(key=[a#5], functions=[max(b#6)], output=[max(b)#17])
+- *Sort [a#5 ASC], false, 0
   +- Exchange hashpartitioning(a#5, 200)
      +- SortAggregate(key=[a#5], functions=[partial_max(b#6)], output=[a#5, max#19])
         +- LocalTableScan [a#5, b#6]
```
Actually, a correct plan is:
```
== Physical Plan ==
SortAggregate(key=[a#5], functions=[max(b#6)], output=[max(b)#17])
+- *Sort [a#5 ASC], false, 0
   +- Exchange hashpartitioning(a#5, 200)
      +- SortAggregate(key=[a#5], functions=[partial_max(b#6)], output=[a#5, max#19])
         +- *Sort [a#5 ASC], false, 0
            +- LocalTableScan [a#5, b#6]
```

## How was this patch tested?
Added tests in `PlannerSuite`.
