Jarin, I think this was incorrectly ported during f5d42d04 (r31561), but it may
have been deliberate. Any thoughts?

None of the asm.js benchmarks actually seem to hit this code at the moment; I
noticed it whilst rebasing something else.

Thanks,
Jacob

You are right, I was not careful enough. Thanks for fixing this!

lgtm.
