Add a DIE_OOPS and DIE_MACHINE_CHECK notify_die hook and remove some
redundant debugger* hooks.

As far as I can see, at the moment there is just one thing that gets
registered to be called by die_notify, and that is
kprobe_exceptions_notify.  It doesn't do anything with DIE_OOPS or
DIE_MACHINE_CHECK.

I would rather get rid of die_notify and have a kprobe_notify instead
that just directly calls kprobe_exceptions_notify.  In fact having
separate kprobe routines for the different events would be even
better.

It's not like our cpus are particularly good at indirect functions
calls... ;(

See the patch I posted a few days ago for the pagefault path..
