// This is pretty fiddly. What we are trying to test here is a specific path
// in the bailout code which needs to know which ICScript to load, and has to
// decide between the script's own ICScript, or the trial-inlined ICScript
// which belongs to the outer script. It uses the ICFallbackStub's
// trialInliningState to make this decision, which can change out from
// underneath us if the inlined call fails. So what were doing here is getting
// into a state where we've monomorphic inlined a function, and gone to Ion
// with it. We then cause the inlined call to fail by calling a function which
// doesn't match what we expect, which transitions us to a failed
// trialInliningState. We then will bail out *inside* bar, due to the
// previously unseen inside of the result >= fns.length check, exercising the
// bailout code in question.
