Use the original arg length of wrapped CP funcs, still call the wrapper

ComputedPropertyPrototype.set analyzes the length of CP arguments to
decide how the CP function should be called. Since the wrapper (which
sets up _super) handles arbitrary arguments, the original function (at
wrappedFunction) should be inspected for .length. The wrapper, however,
should still be called when performing the set (ensuring that _super is
present).

Fixes #2890
Expose `options` arg in `debugger` HB helper

Without this, you can't look up template data and other important pieces of data. (`arguments` is optimized away in Chrome since the function makes no other reference to it)

Support object with `Ember.String.fmt`

* before:

``` javascript
'data: %@'.fmt({id: 3}); //=> 'data: [object Object]'
```

* after:

``` javascript
'data: %@'.fmt({id: 3}); //=> 'data: {a: 1}'
```

This commit improves assertion message such as the following:

``` javascript
Ember.assert('Your data must contain `id`. But actual: %@'.fmt(data), data.id);
