This change breaks extparam processing up into: - propagateExtendedParams: propagates min_length, min_offset and max_offset into the reports on the graph - reduceExtendedParams: runs graph reductions based on extparams Then, we apply the reduce pass to the whole graph, and later as well to each component after calc_components.
