You have full control over optimization phases that Graal performs: When
Graal is invoked for Truffle [1], the "suites" parameter specifies the
optimization phases that are applied. For Truffle, we use the default
suites [2], but you can do any modification to the suites that you want,
i.e., remove phases or add your own custom phases.
