Department of marginal improvements: teach tupconvert.c to avoid doing a
physical conversion when there are dropped columns in the same places in
the input and output tupdescs.  This avoids possible performance loss from
the recent patch to improve dropped-column handling, in some cases where
the old code would have worked.
