This CL is part of a series that makes SwissNameDictionary available
as a new property backing store. Previously, the flag
v8_dict_mode_prototypes allows selecting between NameDictionary and
OrderedNameDictionary as the backing store used for all dictionary
mode objects. This series of CLs changes this such that enabling the
flag causes SwissNameDictionary being used instead of
OrderedNameDictionary. The behavior for when the flag is not set
remains unchanged (= use NameDictionary).
This particular CL just collects many small changes, including some
CSA changes where runtime calls are necessary.
