Robert Haas 80c79ab2a8 pgstattuple: Use SnapshotDirty, not SnapshotNow.
Tuples belonging to uncommitted transactions should not be
counted as dead.

This is arguably a bug fix that should be back-patched, but
as no one ever noticed until it came time to try to get rid
of SnapshotNow, I'm only doing this in master for now.
