This is part of a larger effort to get the Stream code moved up to Support. I don't want to do it in one large patch, in part because the changes are so big that it will treat everything as file deletions and add, losing history in the process. Aside from that though, it's just a good idea in general to make small changes. So this change only changes the names of the Stream related source files, and applies necessary source fix ups. llvm-svn: 296211
