Actually, I realized this morning that there isn't anything there that
the current code doesn't do already. A subxact will never be assigned
an XID in the first place unless it stores tuples into the database.
(This means the do-I-need-to-do-something tests in
RecordSubTransactionCommit and RecordSubTransactionAbort are pretty much
redundant...)
So you might as well drop it from TODO --- perhaps there are variant
ideas we could use, but I don't know what they are.
