[TypeFeedbackVector] Root literal arrays in function literals slots Literal arrays and feedback vectors for a function can be garbage collected if we don't have a rooted closure for the function, which happens often. It's expensive to come back from this (recreating boilerplates and gathering feedback again), and the cost is disproportionate if the function was inlined into optimized code. To guard against losing these arrays when we need them, we'll now create literal arrays when creating the feedback vector for the outer closure, and root them strongly in that vector.
