alpha: take SIGPENDING/NOTIFY_RESUME loop into signal.c
Turn the slow side of work_pending into C function, including all
the looping. What we get out of that:
* we do _not_ call get_signal_to_deliver() with IRQs disabled
anymore
* no need to save/restore volatiles on each pass if there
turns to be more than one (unlikely, but still)
* all double-restart prevention is in C now.
* glue gets simpler.
