Reuse native methods in array internal modules when possible

See #1525 — there's lots of more internals modules with the same issues.

First we should check that they're generic and have no browser bugs, then we should add [].{ method } || to the export entries in these array-* modules.

I'm tracking this issue as I've found there's lots of more functions with the same moments, but I don't personally have the time to audit each of them.

We'll see, maybe I'll be able to make a PR.
