CPU: Check that the interrupt controller is created when needed

This patch adds a creation-time check to the CPU to ensure that the
interrupt controller is created for the cases where it is needed,
i.e. if the CPU is not being switched in later and not a checker CPU.

The patch also adds the "createInterruptController" call to a number
of the regression scripts.
