Review comment:
`RexUtil.gatherTableReferences` returns `Set<RelTableRef>` and not
Set<RexTableInputRef>. `RelTableRef` does not contains the index of this
InputRef in the TS schema which is required to identify if the
`RexTableInputRef` instance refers a partition column or not.
`RelOptHiveTable.getPartColInfoMap()` contains the indexes not the instances.
The RexTableInputRef index is also required by
`HiveCardinalityPreservingJoinOptimization` that is why I extarcted
`findRexTableInputRefs`.
