Timer test assumes that timer 0 IRQ has level 1 and other timers have higher level IRQs. This assumption is not correct and the levels may be arbitrary. Fix that assumption by providing TIMER*_VECTOR macro and using it for vector selection and by making the check for the timer exception cause conditional.
