It's speculative, will revert the revert if this doesn't fix.

Hmm... it's cycled green before this revert lands (though there has been
flakiness). I'll revert this revert after a few more cycles and continue to
watch the tree

Ok, after the first revert the CrOS (x86) ASAN succeeded 3 times in a row, and
after reverting the revert it started failing again.

So I assume my first revert was probably right.  Will be reverting this again...
sorry!
