Reschedule code to read ar.bsp as early as possible. To enable this,
don't bother clearing some of the registers when we're returning to
kernel stacks. Also, instead of trying to support the pNonSys case
(which makes no sense), do a bugcheck instead (with break 0). Finally,
remove a clear of r14 which is a left-over from the previous patch.
