Remove hidden value tracking of event listeners. It duplicates work done by wrapper tracing. This change: - reduces time spent in a microbenchmark of add/removeEventListener by 30% (approximately, measured on Linux) - simplifies code (including removing some custom callback epilogues) - avoids the need for an additional internal field on EventTarget (other than Node) wrappers Change-Id: I06023a6bb01ac54bb9e514def17c0aaf4ae50bf0 Reviewed-on: https://chromium-review.googlesource.com/576472 Commit-Queue: Jeremy Roman <jbroman@chromium.org> Reviewed-by: Michael Lippautz <mlippautz@chromium.org> Cr-Commit-Position: refs/heads/master@{#491479}
