Setup String objects without the accessors
Setup String objects without the accessors

This is safe to do here since we don't setup any Ruby objects, but only
immediates. This prevents a lot of calls into update_handle, since that
is done for the attributes of a String. In systems allocated a lot of
String objects, this shows up as significant in profiles.
