Revert of [heap] Ensure progress when incrementally marking wrappers (patchset #3 id:60001 of https://codereview.chromium.org/2592403002/ ) Reason for revert: This won't work because the finalization still checks whether both marking deques are empty, also calling into blink. So we never proceed there. Original issue's description: > [heap] Ensure progress when incrementally marking wrappers > > The problem here is estimating the marking step size for wrapper tracing. If the > steps are too small, we cannot keep up with the mutator creating new wrappers. > The result is an endless stream of incremental marking steps, alternating v8 and > wrappers tracing, without ever finalizing in a GC. > > The mitigation here is to abort finding the fix point after 10 incremental > iterations. > > A proper solution would track newly created wrappers on the blink side during > wrapper tracing. Will give this more thought after the holidays. > > BUG=chromium:668164, chromium:468240 > > Review-Url: https://codereview.chromium.org/2592403002 > Cr-Commit-Position: refs/heads/master@{#41923} > Committed: https://chromium.googlesource.com/v8/v8/+/a47417b89373c615f9256800cfc803d84ba58378 TBR=ulan@chromium.org # Skipping CQ checks because original CL landed less than 1 days ago.
