[SPARK-17270][SQL] Move object optimization rules into its own file
## What changes were proposed in this pull request?
As part of breaking Optimizer.scala apart, this patch moves various Dataset
object optimization rules into a single file. I'm submitting separate pull
requests so we can more easily merge this in branch-2.0 to simplify optimizer
backports.
## How was this patch tested?
This should be covered by existing tests.
