Reland "[heap] Introduce LocalIsolate for main thread"
This is a reland of e95e1b62 After landing https://crrev.com/c/2546682, this CL can be relanded without changes. Original change's description: > [heap] Introduce LocalIsolate for main thread > > Add a LocalIsolate for the main thread to Isolate. This LocalIsolate is > kept alive during the whole lifetime of the Isolate. The main thread > LocalIsolate starts in the Running state in contrast to the background > thread LocalIsolates (those start in Parked). > > Code paths in Turbofan that used to create a LocalIsolate on the main > thread can now simply use the main thread LocalIsolate. > > LocalIsolate for the main thread will help in reducing differences > between the main and background threads. The goal is that the main > thread behaves more like a background thread. > > The main thread LocalIsolate should also make it simpler to share code > between main thread and background threads by using LocalIsolate for > both. > > Bug: v8:10315 > Change-Id: I7fd61d305a6fd7079e2319d75c291c1021e70018 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2509593 > Reviewed-by: Simon Zünd <szuend@chromium.org> > Reviewed-by: Yang Guo <yangguo@chromium.org> > Reviewed-by: Ulan Degenbaev <ulan@chromium.org> > Reviewed-by: Leszek Swirski <leszeks@chromium.org> > Reviewed-by: Georg Neis <neis@chromium.org> > Commit-Queue: Dominik Inführ <dinfuehr@chromium.org> > Cr-Commit-Position: refs/heads/master@{#71226} Bug: v8:10315 Change-Id: I418b1217aeac4f3c44a0aa514dea9864f8a58656 TBR: szuend@chromium.org, yangguo@chromium.org, ulan@chromium.org, leszeks@chromium.org, neis@chromium.org Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2543399Reviewed-by: Dominik Inführ <dinfuehr@chromium.org> Commit-Queue: Dominik Inführ <dinfuehr@chromium.org> Cr-Commit-Position: refs/heads/master@{#71274}
