23afc2c4ec Back out the previous change on this branch. In its place: Determine the
affinity of a subquery by the left-most arm of the subquery that has an
affinity other than NONE.  In other words, scan from left to right looking
for an arm of the compound subquery with an affinity of BLOB, TEXT, INTEGER,
or REAL and pick the first one found.  Or stay with NONE if no arm has a
defined affinity.  Test cases added.

d21d5b21db The read-only CHECK-constraint optimization of [34ddf02d3d21151b] inhibits the
xfer optimization for tables with CHECK constraints.  However, the xfer
optimization is required for correct operation of VACUUM INTO on tables that
contain generated columns. Fix this by ignoring CHECK constraints when
qualifying the xfer optimization while running VACUUM.  Problem reported by
