TBR.
Let us see if anything changed since my last attempt. IIRC there've been changes
on v8 side that could've fixed the problems with 32-bit builds.

No LGTM from a valid reviewer yet. Only full committers are accepted.
Even if an LGTM may have been provided, it was from a non-committer,
_not_ a full super star committer.

Try jobs failed on following builders:
  ios_dbg_simulator on tryserver.chromium.mac (JOB_TIMED_OUT, no build URL)
  ios_rel_device_ng on tryserver.chromium.mac (JOB_TIMED_OUT, no build URL)
  ios_rel_device_ninja_ng on tryserver.chromium.mac (JOB_TIMED_OUT, no build
URL)
Timed out jobs are not retried to avoid causing additional load on the builders
with large pending queues.
