I don't think that testing rowMarks is the right thing at all here.
That tells you whether it's a SELECT FOR UPDATE, but actually we
want any cursor (and only cursors) to have a private snapshot.

Also, do we really need the Register bit?  Won't the portal register
its use of the snapshot anyway (or if it doesn't, isn't that a bug)?
