Subject: [PATCH] I am experimenting with putting visibility-default attributes
 on all struct/classes in libc++.  This checkin decorates only basic_string
 and vector as an experiment, and for review by those in this audience that
 might know more about visibilty than I do.  If I get no negative feedback on
 this procedure I will begin to decorate the entire library in this way.
