hablich aa8a208a47 Revert of [TypeFeedbackVector] Root literal arrays in function literals slots (patchset #11 id:370001 of https://codereview.chromium.org/2504153002/ )
Reason for revert:
Speculative revert because of blocked roll: https://codereview.chromium.org/2596013002/

Original issue's description:
> [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.
