deps: V8: cherry-pick cb4faa902e9f

Original commit message: Reland "[liftoff][arm64] Use 64 bit offset reg in mem op" This is a reland of f645d0b857bc669271adcbe95cf25e1554347dd4 The issue was that converting an i64 to an i32 didn't clear the upper bits on arm64. This was not necessary before because we did the zero extension as part of the load operand, but this is required now that we use the full register. Original change's description: > [liftoff][arm64] Use 64 bit offset reg in mem op > > Accessing the Wasm memory with a 64 bit offset was truncated to 32 bit, > which is fine if we check bounds first, but not if we rely on the > trap handler to catch the OOB. > > R=clemensb@chromium.org > > Bug: v8:11587 > Change-Id: I82a3a2906e55d9d640c30e770a5c93532e3a442c > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2808942 > Reviewed-by: Clemens Backes <clemensb@chromium.org> > Commit-Queue: Thibaud Michaud <thibaudm@chromium.org> > Cr-Commit-Position: refs/heads/master@{#73829} Bug: v8:11587 Change-Id: Ibc182475745c6f697a0ba6d75c260b74ddf8fe52 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2810846 Reviewed-by: Clemens Backes <clemensb@chromium.org> Commit-Queue: Thibaud Michaud <thibaudm@chromium.org> Cr-Commit-Position: refs/heads/master@{#73853} Refs: v8/v8@cb4faa9 PR-URL: #39337 Reviewed-By: Matteo Collina <matteo.collina@gmail.com> Reviewed-By: James M Snell <jasnell@gmail.com>
