New issue 3977 by [email protected]: when new.target is available,
extra variable prepended to rest parameters
https://code.google.com/p/v8/issues/detail?id=3977
Seems to be prepending undefined `this` variable to rest parameters when
building the rest parameters array
```
Echo:v8 caitp$ out/x64.debug/d8 --harmony-rest-parameters --harmony-classes
--use-strict
V8 version 4.3.0 (candidate) [console: dumb]
d8> class A { constructor(...a) { this.a = a; } }
class A { constructor(...a) { this.a = a; } }
d8> class B extends A { constructor(...b) { super(b); this.b = b; } }
class B extends A { constructor(...b) { super(b); this.b = b; } }
d8> new B(1, 2, 3)
{a: [[, 1, 2, 3]], b: [, 1, 2, 3]}
d8>
d8> new A(1, 2, 3)
{a: [1, 2, 3]}
```
