[es6] enable destructuring rest parameters
Originally, only BindingIdentifiers were a legal operand for the `...` ellipsis
in a function rest parameter. This has since changed, allowing the rest array
to be destructured.
The grammar is now the following:
```
FunctionRestParameter[Yield]:
BindingRestElement[?Yield]
BindingRestElement[Yield]:
... BindingIdentifier[?Yield]
... BindingPattern[?Yield]
```
