Constructs a "normal" graph from the constraint set; the graph makes it easy to find the constraints affecting a particular region.
NB: This graph contains a "frozen" view of the current
constraints. any new constraints added to the ConstraintSet
after the graph is built will not be present in the graph.

Like graph
, but constraints a reverse graph where R1: R2
represents an edge R2 -> R1
.

Compute cycles (SCCs) in the graph of regions. In particular, find all regions R1, R2 such that R1: R2 and R2: R1 and group them into an SCC, and find the relationships between SCCs.
