c64f0e71c1 Enhance the TreeView debugging output for Expr with opcode TK_IN so as to 
show the RHS table and the subroutine address.

3d5665366f Enhance the codeEqualityTerm() routine inside the code generator so that it is 
able to reuse an IN operator that has an invariant subquery on its right-hand
side while coding the non-matched loop of a RIGHT JOIN.

609959285b When computing STAT1 values using ANALYZE, if a ratio comes out to be between 
1.0 and 1.1, then round it down to 1 rather than the using the default rounding
rule of changing it to 2.  The reduces the estimation error for the
case where a column value is very nearly, but not quite unique.
