This reverts commit 00a757fa. Reason for revert: Caused perf regressions, https://crbug.com/1280236 Original change's description: > Shorten generated code for binary-search switches > > On some branches of the search tree for a binary-search switch, the > input value is sufficiently constrained that we could unconditionally > jump to the last possible case rather than checking for value equality. > This shortens some builtins by a few instructions and might speed things > up, though I expect the effect to be small. > > Change-Id: I2313f26976e6d3c182f03bd927b338c8175b3af3 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3335437 > Reviewed-by: Nico Hartmann <nicohartmann@chromium.org> > Commit-Queue: Seth Brenith <seth.brenith@microsoft.com> > Cr-Commit-Position: refs/heads/main@{#78376} Bug: chromium:1280236 Change-Id: I88d9ff64641b85d48198b7012df2eeb9441913b5 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3343234 Bot-Commit: Rubber Stamper <rubber-stamper@appspot.gserviceaccount.com> Reviewed-by: Nico Hartmann <nicohartmann@chromium.org> Commit-Queue: Seth Brenith <seth.brenith@microsoft.com> Cr-Commit-Position: refs/heads/main@{#78397}
