Reynold Xin 3d1535d488 [SPARK-9520] [SQL] Support in-place sort in UnsafeFixedWidthAggregationMap
This pull request adds a sortedIterator method to UnsafeFixedWidthAggregationMap that sorts its data in-place by the grouping key.

This is needed so we can fallback to external sorting for aggregation.
