832ee3d4cc Optimize the degenerate case of a FROM clause table name enclosed all by 
itself inside parentheses.  Generate code as if the parentheses did not
exist, rather than the old behavior of manifesting the parenthesized table
into a transient table.  Also, tag every FROM-clause SELECT subquery that is
generated by a parenthesized FROM-clause expression using the SF_NestedFrom
flag.  The new SF_NestedFrom flag is not yet used for anything.

468ef9a87e 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.
