commit 9b6429d142abd3975c3213505ec351701636464a
Author: Ruslan Zakirov <ruz at bestpractical.com>
Date: Wed May 8 13:58:48 2013 +0400
replace NewAlias with Join calls
Join method does NewAlias for us and it makes next code
easier to implement.
Not all NewAlias calls are replaced with Join, only those
that can benefit from explicit DISTINCT argument and
code that auto guess join DISTINCTness.

we can auto mark Join as distinct in some cases
If we join to a table and in target table we join to id
then join is distinct.
