Honor strong intra-component target dependencies

Strong dependencies (created by add_dependencies) must be honored when
linearizing a strongly-connected component of the target dependency
graph.  The initial graph edges have strong/weak labels and can contain
cycles that do not consist exclusively of strong edges.  The final graph
never contains cycles so all edges can be strong.
