PPC: [es6] Support super.property in eval and arrow functions

Port 44e9810345cea9bfd6861905bc6856db7db5a25c

Original commit message:
When we enter a method that needs access to the [[HomeObject]]
we allocate a local variable `.home_object` and assign it the
value from the [[HomeObject]] private symbol. Something along
the lines of:

  method() {
    var .home_object = %ThisFunction()[home_object_symbol];
    ...
  }
