This behavior changed recently. SharedArrayBuffers should not be put in the
transfer list, because they are not detached, and that is the meaning of being
in the transfer list.

This is the V8 side of the change, the Blink side will come next.

Reland of https://codereview.chromium.org/2570433005, it was reverted because
of a Blink-side test failure which has been temporarily disabled; see
https://codereview.chromium.org/2590003002.
