Committed patchset #2 (id:20001) as
https://chromium.googlesource.com/chromium/src/+/7417bea53a78a97ae815479e5d73...

[xlai (Olivia), 2017-01-12 19:48:35]

A revert of this CL (patchset #2 id:20001) has been created in
https://codereview.chromium.org/2631543002/ by xlai@chromium.org.

The reason for reverting is: Suspecting this CL is causing these tests to fail:
fast/workers/worker-shared-asm-buffer.html
virtual/sharedarraybuffer/fast/workers/worker-shared-asm-buffer.html

From the layout test results, it seems that turning on asm.js will append some
console results to the test outcome.
Example build:
