Igor Babaev 715dc5f99d Fixed a cost estimation bug introduced into in the function best_access_path ...

of the 5.3 code line after a merge with 5.2 on 2010-10-28
in order not to allow the cost to access a joined table to be equal
to 0 ever.

Expanded data sets for many test cases to get the same execution plans
as before.
