Adding a %SimulateNewspaceFull runtime function speeds up this test from 7m21s to 0.3s (on arm.optdebug with --jitless). Bonus content: - speed up mjsunit/md5 by 23x (5m25s -> 7.5s) - speed up mjsunit/string-replace-gc by 8x (1m37s -> 12s) Bug: v8:9700, v8:9396 Change-Id: Id00d0b83b51192edf1d5493b49b79b5d76e78087 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1807355 Reviewed-by: Ulan Degenbaev <ulan@chromium.org> Commit-Queue: Jakob Kummerow <jkummerow@chromium.org> Cr-Commit-Position: refs/heads/master@{#63829}
