[Optimisation] - Zero cost arguments, create argument objects lazily about boa

[Razican]

Hi @jasonwilliams could you please give a bit more insight on what should be done here?

[jasonwilliams]

So i think this needs discussion, as i don't have a solution right now.
Basically every time a function is called an arguments object is created, so this degraded performance quite a bit.

There was an idea to only create the arguments object if its used.

Im going to close this as i think we've refactored quite a bit since this was made
