I haven't converted cctests and map->prototype() yet
Description:
Introduce a PrototypeIterator template and use it all over the place
The idea is to have one central place where all prototype access happens.
The different template parameters specialize on
- How to objects are stored (raw pointer vs handle)
- Whether we walk the prototype chain based on the map, or via a type switch
- Where the prototype chain ends (null value, non hidden prototype,
given object)
A macro is provided for the common case that only the first prototype is
accessed.
