[JSC] Add dumpIonGraph option
https://bugs.webkit.org/show_bug.cgi?id=304863
rdar://167451770
Reviewed by Keith Miller.
This patch adds dumpIonGraph option, which generates IonGraph[1] that is
IR debugging format used in SpiderMonkey.
https://mozilla-spidermonkey.github.io/iongraph/ can visualize this
format so that we can easily see the entire CFG phase by phase.
Right now, JSC DFG / FTL / B3 / Air has more flexibility in CFG, for
example JSC CFG can have multiple entrypoints. These difference makes
IonGraph web page sometimes does not work, so right now we are using a
bit customized one, which will be pushed after approval.
