qemu_irq_intercept_in() saves original IRQ handlers by allocating new QOM objects, which are never freed. On a PC machine, this leaks IRQ objects (one per IOAPIC pin) on every qtest run. Rather than tracking allocations to free later, avoid them: add an "observer" field to IRQState, called by qemu_set_irq() after the real handler. Interception sets the observer instead of rewriting handlers, so there's nothing to save and nothing to leak. Fix qemu_notirq() to route through qemu_set_irq() so inverted IRQs trigger observers too. Drop the LSan suppression.
