[Bug middle-end/21474] missed optimizations when comparing address to NULL

I think it is odd that if you call subr(i,0), it doesn't crash, that is &(p->a)
does not actually dereferences p. Nonetheless, I agree that the behaviour seems
inconsistent. A nice little project for someone. As they say, patches welcome!
