Enable the runlatch at the start of each exception. Unfortunately we are out of space in the 0x300 handler, so I added it a bit later. The SPR write is fairly expensive, perhaps we should cache the runlatch state in the paca and avoid the write when possible. We don't need to turn the runlatch off, we do that in the idle loop. Better to take the hit in the idle loop than for each exception exit.
