Along the way: - Thread isolate parameter explicitly through code that used to rely on getting it from the zone. - Canonicalize the parameter position of isolate and zone for affected code - Change Hydrogen New<> instruction templates to automatically pass isolate R=mstarzinger@chromium.org LOG=N Review URL: https://codereview.chromium.org/868883002 Cr-Commit-Position: refs/heads/master@{#26252}
