The new ObjectPtr design makes non-inlined helper functions a little more expensive because "this" is always a pointer where pass-by-value would be more efficient, which is an issue for functions whose size puts them right at the threshold of getting inlined or not. String::Get falls into this category when called from RegExpFlagsFromString. In this case, we can do even better than restoring inlineability by fine-tuning the control flow a bit. This should repair the regression in crbug.com/910573 Bug: chromium:910573 Change-Id: Ie6b68ef01cd978ec502d8d6c1da788c77422dce7 Reviewed-on: https://chromium-review.googlesource.com/c/1369087 Commit-Queue: Jakob Kummerow <jkummerow@chromium.org> Reviewed-by: Yang Guo <yangguo@chromium.org> Cr-Commit-Position: refs/heads/master@{#58234}

Defining the subclass within the loop significantly affects subsequent test results. For instance, the Search benchmark is 50% slower if the subclass is defined within the loop. BUG=v8:5339 Review-Url: https://codereview.chromium.org/2537253003 Cr-Commit-Position: refs/heads/master@{#41384}
