33e619fc1c Additional refinements to Expr handling. Restore compression of trigger 
expressions.  Change Expr.zToken to Expr.u.zToken and added Expr.u.iValue.
Remove an unnecessary ExprDup from CHECK constraint processing.  And so forth. (CVS 6682)

b7916a78ff Simplifications to the Expr object: Remove Expr.span completely and convert 
Expr.token into a char* Expr.zToken.  Also simplify the Token object by
removing the Token.dyn and Token.quoted fields. (CVS 6681)

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)
