Re-ship Harmony Array/TypedArray methods

Re-ship Harmony Array/TypedArray methods

Turning the --harmony-array flag on has been delayed behind
unrelated test failures. Now that those tests are disabled,
land the changes.

This patch fixes WebKit tests based on the new change.

I see one Mac asan failure, but it looks completely unrelated:

http://build.chromium.org/p/client.v8/builders/V8%20Mac64%20ASAN/builds/1799/....

Also, it did not fail the last time this landed. So I'm inclined to keep this in
the tree, hoping it'll pass on the next run.
