object ExtractFiltersAndInnerJoins extends PredicateHelper

This we have to copy from spark patterns.scala because we want handle single table with filters as well.

This will have another advantage later if we decide to move our rule to the last instead of injecting just after ReorderJoin, whereby additional nodes like Project requires handling.
