Also, is it necessary to have the TransactionIdEquals() tests in both
HeapCheckForSerializableConflictOut() and
CheckForSerializableConflictOut()? Apart from anything else, the test
in HeapCheckForSerializableConflictOut() occurs before we establish
the topmost XID -- it could be a subxid, in which case the test is
wrong. Though it doesn't actually matter on account of the redundancy,
IIUC.
