cpu: Probe points for basic PMU stats
This changeset adds probe points that can be used to implement PMU counters for CPU stats. The following probes are supported: * BaseCPU::ppCycles / Cycles * BaseCPU::ppRetiredInsts / RetiredInsts * BaseCPU::ppRetiredLoads / RetiredLoads * BaseCPU::ppRetiredStores / RetiredStores * BaseCPU::ppRetiredBranches RetiredBranches
