Zampetakis, Impala Public Jenkins,

to look at the new patch set (#3).
Change subject: IMPALA-15243: Fix costing for CTEs
......................................................................
IMPALA-15243: Fix costing for CTEs
Addresses missing elements in plan costing when
COMPUTE_PROCESSING_COST=true.
Notably TPC-DS Q39 contains fragments with CTEConsumerNodes and no
ScanNodes, some of which have no child fragments because only the first
CTEConsumerNode contains a link to its producer to avoid creating a DAG.
This may affect the efficacy of CPC with CTEs.
