Ignore all Data Dependency calculations if Algorithm is a Sequence

If an Algorithm is a Sequence, the scheduler pays no attention to the data dependency rules, and just does control flow. So there's no need to do any data dependency calculations, or filter the dependency loops, for which, by definition, there will be.

The ugly bit is that we have to check for the existence of the Property "IgnoreFilterPassed", as there's no good way of determining if an Alg is a Sequence.
