The arm exception entry points currently vector through a function pointer

to the actual handler routine.  All the pointers are static-intialized to
the only handlers available, and yet various platform-specific inits still
set those pointers (to the values they're already initialized to).  Begin
to drain the swamp by removing all the redundant external declarations and
runtime setting of the pointers that's scattered around various places.
