   Move PartitionPruneInfo out of plan nodes into PlannedStmt

I think the attached is the correct fix.  I also wonder if it's worth
an isolation test to exercise this code.

Thanks for the patch, David, and for the report, Fei.  I indeed forgot
to update EvalPlanQualStart() in that commit.

I agree about adding an isolation test, which I have done in the
attached updated patch.
