[SPARK-20612][SQL][WIP] Throw exception when there is unresolvable
attributes in Filter
## What changes were proposed in this pull request?
We have a rule in `Analyzer` that adds missing attributes in a Filter into
its child plan. It makes the following codes work:
val df = Seq((1, "a"), (2, "b"), (3, "c")).toDF("x", "y")
df.select("y").where("x=1")
It should throw an analysis exception instead of implicitly adding the
missing attributes into underlying plan.
## How was this patch tested?
Jenkins tests.
