With bytecode flushing and lazy feedback allocation, we need to call %PrepareForOptimization before we call %OptimizeFunctionOnNextCall, ideally after declaring the function. Bug: v8:8801, v8:8394, v8:9183 Change-Id: I3fb257282a30f6526a376a3afdedb44786320d34 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1648255 Commit-Queue: Mathias Bynens <mathias@chromium.org> Reviewed-by: Maya Lekova <mslekova@chromium.org> Reviewed-by: Mythri Alle <mythria@chromium.org> Cr-Commit-Position: refs/heads/master@{#62119}
