This CL changes the "small" versions of ordered hash tables, like
SmallOrderedNameDictionary and the corresponding handlers, like
OrderedNameDictionaryHandler, to use InternalIndex rather than int
as the type used for indices.
This is part of an effort to make the interfaces of the
ordered and unordered name dictionaries more similar.

This changes the ordered hash data structures in ordered-hash-table.h to
use InternalIndex as the type used for indices, rather than int.
This makes the interface more similar to the (unordered) hash tables in
dictionary.h and hash-table.h

This changes OrderedHashMap, OrderedHashSet, and OrderedNameDictionary
as follows:
- Create a dedicated allocation function AllocateEmpty to create zero-
element instances of these classes
- Fix bugs resulting from using these zero-element versions
Further, this CL
- provides a canonical empty versions of OrderedNameDictionary
- changes the types of the canonical ordered hash table and hash set
from FixedArray to the actual subclasses

Remove Isolate parameters from some dictionary methods, and change
others to use ReadOnlyRoots instead, to prepare for Isolate
templatization in a future patch.
One small side-effect is that the global dictionary's property cell's
dependent code deoptimization has to dynamically get the Isolate when
it needs to actually mark code for deoptimization, for method signature
consistency. Given that this is the slow path anyway, it shouldn't
matter.

This change allows the KeyAccumulator to throw a range error if there

This CL introduces extensive checks during key enumeration in the run-time,
and might introduce regressions. If so, feel free to revert.

All operations on the two ordered hash tables must be performed
