dS)	a[Fixer for 'raise E, V, T'

raise         -> raise
raise E       -> raise E
raise E, V    -> raise E(V)
raise E, V, T -> raise E(V).with_traceback(T)
raise E, None, T -> raise E.with_traceback(T)

raise (((E, E'), E''), E'''), V -> raise E(V)
raise "foo", V, T               -> warns about string exceptions


CAVEATS:
1) "raise E, V" will be incorrectly translated if V is an exception
   instance. The correct Python 3 idiom is

        raise E from V

   but since we can't detect instance-hood by syntax alone and since
   any client code would have to be changed as well, we don't automate
   this.
