Refactor collating-sequence handling as a fix for ticket [71e333e7d2e642]. The Expr.pColl field is removed from the Expr object. The COLLATE operator now becomes a separate instance of Expr in the expression tree. The code generator looks up the correct collating function as needed, rather than referring to Expr.pColl.

Make sure WHERE clause constraints A=B and B=A work the same even with COLLATE clauses. (check-in: b3f53668 user: drh tags: ticket-71e333e7)
