cpu-o3: Move general fetch stats to BaseCPU::FetchCPUStats

Browse Source 
The stats moved are from fetch.hh and fetch.cc of O3. Stat branches is
now tracked by numBranches. Stat branchRate is now tracked by
branchRate in FetchCPUStats. Stat rate is tracked by fetchRate. Stat
insts is tracked by numInsts. Stat icacheStallCycles is tracked by
icacheStallCycles in FetchCPUStats.
