1450bc6e52 Avoid storing the result register for EXISTS and SELECT in any field of
the Expr object - simply return the register number as the return value
of the function that codes those expressions.

6a2fe09387 Generalize the IS and IS NOT operators so that their right-hand side can be
an arbitrary expression and not simple the constant NULL.  They work like
= and <> except that NULL values compare equal to one another an unequal to
everything else.

c4a64facce Rework the logic that generates a schema for tables created using
"CREATE TABLE ... AS SELECT ...".  Instead of trying to copy the raw
datatype string from the right-hand side, just make the type one 
of TEXT, INT, REAL, NUM, or nothing.  This is much simpler than 
trying to parse and quote datatype strings.  Other minor 
implifications to build.c are bundled with this change. (CVS 6626)
