x86: replace nr_irqs sized per-domain arrays with radix trees
It would seem possible to fold the two trees into one (making e.g. the
emuirq bits stored in the upper half of the pointer), but I'm not
certain that's worth it as it would make deletion of entries more
cumbersome. Unless pirq-s and emuirq-s were mutually exclusive...
