Revert of base: Make shared memory backed by Mach primitives by default. (patchset #3 id:40001 of https://codereview.chromium.org/1453383002/ )
Reason for revert:
Speculative revert: 3 mac perf bots started timing out in random tests around the time this patch landed. I'll keep an eye on the waterfall and reland if things don't improve.
