ss_currentScanDesc_20100226.patch (application/octet-stream) patch

ScanState.ss_currentScanDesc is currently used by only SeqScan and
BitmapHeapScan. Other scan nodes don't use the field at all, right?

Can we move the field into SeqScanState and BitmapHeapScanState
for code cleanup? This change will not improve any performance,
but it can clear up what we do actually.
