[SPARK-19514] Making range interruptible.

## What changes were proposed in this pull request?

Previously range operator could not be interrupted. For example, using DAGScheduler.cancelStage(...) on a query with range might have been ineffective.

This change adds periodic checks of TaskContext.isInterrupted to codegen version, and InterruptibleOperator to non-codegen version.

I benchmarked the performance of codegen version on a sample query `spark.range(1000L * 1000 * 1000 * 10).count()` and there is no measurable difference.

## How was this patch tested?

Adds a unit test.
