[SPARK-23835][SQL] Add not-null check to Tuples' arguments
## What changes were proposed in this pull request?
There was no check on nullability for arguments of `Tuple`s. This could
lead to have weird behavior when a null value had to be deserialized
into a non-nullable Scala object: in those cases, the `null` got
silently transformed in a valid value (like `-1` for `Int`),
corresponding to the default value we are using in the SQL codebase.
This situation was very likely to happen when deserializing to a Tuple
of primitive Scala types (like Double, Int, ...).
The PR adds the `AssertNotNull` to arguments of tuples which have been
asked to be converted to non-nullable types.

[SPARK-23986][SQL] freshName can generate non-unique names
## What changes were proposed in this pull request?
We are using `CodegenContext.freshName` to get a unique name for any new
variable we are adding. Unfortunately, this method currently fails to
create a unique name when we request more than one instance of variables
with starting name `name1` and an instance with starting name `name11`.
The PR changes the way a new name is generated by
`CodegenContext.freshName` so that we generate unique names in this
scenario too.

[SPARK-23948] Trigger mapstage's job listener in submitMissingTasks
## What changes were proposed in this pull request?
SparkContext submitted a map stage from `submitMapStage` to
`markMapStageJobAsFinished` is called only in
But think about below scenario: 1. stage0 and stage1 are all
`ShuffleMapStage` and stage1 depends on stage0; 2. We submit stage1 by
`submitMapStage`; 3. When stage 1 running, `FetchFailed` happened,
stage0 and stage1 got resubmitted as stage0_1 and stage1_1; 4. When
stage0_1 running, speculated tasks in old stage1 come as succeeded, but
stage1 is not inside `runningStages`. So even though all
splits(including the speculated tasks) in stage1 succeeded, job listener
in stage1 will not be called; 5. stage0_1 finished, stage1_1 starts
running. When `submitMissingTasks`, there is no missing tasks. But in
current code, job listener is not triggered.
We should call the job listener for map stage in `5`.
