Alex Behm 2d9a2e07bd IMPALA-680: Account for existing data partition on lhs and/or rhs of a partitioned join. ...

Impala now exploits existing partitioning of the lhs and/or rhs of joins. Existing
partitioning effects the cost of choosing between a partitioned and a broadcast join,
as well as the final plan because Impala can avoid repartitioning the data.
An existing data partition is exploitable iff the lhs/rhs input partition is equivalent
to the target partition of the join. This matching procedure considers equivalence classes.
