The original code was connecting several outbounds qemu_irqs to the same qemu_irq without using a TYPE_OR_IRQ.
This patch fixes the issue by using OR gates when necessary (1st commit). I attempted to check that the problem is fixed by using a QTest (2nd commit) but actually the test is passing even before the fix : when any fan-in input line is raised, the output is raised too.
