- Register canonical names for internal VM classes and get rid of the method GetSingletonClassName

1. Register canonical names for internal VM classes and get rid of the method GetSingletonClassName
2. Create the empty_array object as a singleton in the VM isolate and remove it from the object store
3. Remove eager population of the functions_cache entry in the class. This results in a pretty impressive reduction of the initial isolate heap size:
    - on IA32 it goes from 1331k to 1071k
    - on X64 it goes from 2431k to 1911k
    - snapshot size also is reduced from 859219 bytes to 789147 bytes.
    (as a follow up change I will consider completely removing functions cache)

Maybe replace all Array::Empty() with Object::empty_array()
