[runtime] Turn ArgumentAccessStub into FastNewSloppyArgumentsStub.

[runtime] Turn ArgumentAccessStub into FastNewSloppyArgumentsStub.

Turn the fast case of ArgumentsAccessStub into a new stub
FastNewSloppyArgumentsStub, which is similar to the existing
FastNewStrictArgumentsStub, although not polished yet, and the slow
case always went to the runtime anyway, so we can just directly emit
a runtime call there.

Hey Michi,

As discussed offline, here's the renaming and the removal of the awesome slow
case in the stub.
Please take a look.

Thanks,
Benedikt
