Revert of [TypeFeedbackVector] Root literal arrays in function literals slots (patchset #7 id:120001 of https://codereview.chromium.org/2620753003/ ) Reason for revert: gc stress: https://build.chromium.org/p/client.v8/builders/V8%20Linux%20-%20gc%20stress/builds/8105 also on mac 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. > > BUG=v8:5456 > > Review-Url: https://codereview.chromium.org/2620753003 > Cr-Commit-Position: refs/heads/master@{#42258} > Committed: https://chromium.googlesource.com/v8/v8/+/31887804107bf5c103d915f5c601cfaaf1cd7cb6 TBR=bmeurer@chromium.org,mstarzinger@chromium.org,yangguo@chromium.org,mvstanton@chromium.org # Skipping CQ checks because original CL landed less than 1 days ago.
