Reland "Use V8 implementation of ArrayBuffer in Blink".
This is exactly the same patch as in https://codereview.chromium.org/18233012/.
It got reverted from Blink because it failed ExtensionWebRequestApiTest.PostData2
in chromium browser_test. The problem with that test has been identified
(http://crbug.com/257128), the test will be disabled before the Blink roll and
updated afterwards.
