Add receiver parameter to object internal methods

[tofpie]

This Pull Request fixes #1040.

It changes the following:

• Add the receiver parameter [[Get]] and [[Set]]
• Make Array more compliant by using [DefineOwnProperty]] instead of [[Set]] to define new indexed properties
• Add Array specific [[DefineOwnProperty]]
• Add compliant [[SetPrototypeOf]] (with cycle detection)
• Make name and length of functions writable

I'm confused, GH won't let me request reviews from @HalidOdat and @Razican so I'l tag you instead...

[Razican]

Looking good for me! Check the review by @RageKnify. I just had a small question.
