Back-patch Heikki's fix to make TransactionIdIsCurrentTransactionId() use
binary search instead of linear search when checking child-transaction XIDs.
Per example from Robert Treat, the speed of TransactionIdIsCurrentTransactionId
is significantly more important in 8.3 than it was in prior releases, so
this seems worth taking back-patching risk for.
