deps: V8: cherry-pick 6771d3e31883
Original commit message: [wasm][liftoff][cleanup] Remove default parameter of GetUnusedRegister This CL removes the default parameter of GetUnusedRegister to avoid bugs where the default parameter is used accidentially. With "{}" the default value of the parameter is easy to write, and also not much more difficult to read. R=clemensb@chromium.org Bug: v8:10506 Change-Id: I3debe5eb91578c82abdac81dc6c252435fdf30d6 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2202991 Reviewed-by: Clemens Backes <clemensb@chromium.org> Commit-Queue: Andreas Haas <ahaas@chromium.org> Cr-Commit-Position: refs/heads/master@{#67822} Refs: v8/v8@6771d3e PR-URL: #38275 Reviewed-By: Matteo Collina <matteo.collina@gmail.com> Reviewed-By: Jiawen Geng <technicalcute@gmail.com> Reviewed-By: Shelley Vohr <codebytere@gmail.com>
