Use uncached addresses for all exception vectors, when copying our code (or
trampolines) to them; this makes sure there is no risk of pending writes
being lost when we clear the caches. Of course, this would be a bug in the
cache handling routines, but having our vectors correctly set will help
debugging the issue.
Tested on sgi and loongson.
