/* diagnostics::digraphs provides support for directed graphs.

   diagnostics::state_graphs provides a way to extend these graphs
   for representing "state graphs" i.e. a representation of the state
   of memory inside a program, for use e.g. by -fanalyzer.

   Specifically, nodes represent memory regions, and we use property bags
   in these nodes to stash extra properties (e.g. what kind of memory region
   a node is e.g. stack vs heap).  */
