Original change's description:
> [runtime] Adds LocalNameIterator
>
> ScopeInfo will contain either inlined (array) local names or
> a hash table (names => index) containing the local names.
>
> We abstract iteration with LocalNameIterator and remove
> ContextLocalName since accessing a local name by index in
> the hash table would be expensive.
>
> This CL only implements the iterator for the array.
