[PATCH] D39819: [cfi-verify] Add DOT graph printing for GraphResult objects.

[Mitch Phillips via Phabricator via llvm-commits]

hctim created this revision.

Allows users to view GraphResult objects in a DOT directed-graph format. This feature can be turned on through the `--print-graphs` flag.

Also enabled pretty-printing of instructions in output. Together these features make analysis of unprotected CF instructions much easier by providing a visual control flow graph.
