  [JSC] Include JSC-fork of IonGraph

Reviewed by Mark Lam.

This patch includes JSC-fork of IonGraph[1], control flow graph
visualizer for JSC's compiler IRs. This is useful for debugging and
optimization. We tweaked SpiderMonkey's IonGraph to make it work for
JSC's graph data. This will be accessible via [2]. Main change is
described in README.md.
