Reviewers: Mads Ager, antonm,
Description:
Reapplying r5147 (caching maps for slow case objects).
r5147 wrongly assumed that a code cache for a slow case map is always empty.
This patch solves this: whenever we attempt to add a stub to a map's code
cache
we check that this map is cached. If it is we give the object its own copy
of the map and only then modify the map.
