[SPARK-9182][SQL] Cast filters are not passed through to datasources
As mentioned in https://issues.apache.org/jira/browse/SPARK-9182,
Some casts filters are not passing to datasources (The original PR was
reverted because of some downcasting issues).
So, for this PR, rather than checking the range or constant-folding, I just
made the actual cast to check if down-casting actually happens.
Test codes and some codes are basically similar with the previous ones
(@yjshen).
The codes are a bit messy and might need to be cleaned up.
@liancheng Could you please review this PR?
