The CTE pointers have to be handled separately in parse tree copy, otherwise they will remain pointing to the CTEs from the old tree.
PT_TREE_COPY_INFO was created to keep a list of cloned CTE nodes in new/old pairs. This list will be used for each CTE pointer to identify the updated CTE node address.
