In order to fit with the "don't-run-spus-outside-of-spu_run" model, this patch starts the isolated-mode loader in spu_run, rather than spu_create. If spu_run is passed an isolated-mode context that isn't in isolated mode state, it will run the loader. This fixes potential races with the isolated SPE app doing a stop-and-signal before the PPE has called spu_run: bugzilla #29111. Also (in conjunction with a mambo patch), this addresses #28565, as we always set the runcntrl register when entering spu_run. It is up to libspe to ensure that isolated-mode apps are cleaned up after running to completion - ie, put the app through the "ISOLATE EXIT" state (see Ch11 of the CBEA).
