Jim Apple d70ffa455d IMPALA-3450: LIMITs on plan nodes are reflected in cardinality estimates
PlanNode includes a 'capAtLimit()' method that can be used in
'computeStats()' on PlanNodes to ensure they do not estimate their
cardinality to be more than a pushed-down LIMIT clause.

This patch ensures that 'capAtLimit()' is used in all of the relevant
classes descending from PlanNode.
