Add an option `exitOnPMUInterrupt` to ArmPMU. The PMU is often used to identify and demark regions of interest in a workload intended for sampled simulation (e.g. fast-forward, warm-up, detailed simulation). Often the PMU is enabled and disabled to demark these regions, but for some workloads PMU interrupts are used to count committed instructions directly. This patch adds the option to exit the simulation loop when a PMU interrupt is triggered so additional simulation control can be effected (e.g. stats dump/reset, CPU switch, etc).
