Check the state of a particular interrupt, ignoring CPSR masks.
This method is primarily used when running the target CPU in a hardware VM (e.g., KVM) to check if interrupts should be delivered upon guest entry.

This function is used to check if a wfi operation should sleep.
If there is an interrupt pending, even if it's masked, wfi doesn't sleep.
