Fix up kernel stats, allow them to not be used as well.
arch/alpha/ev5.cc:
Fix up some stuff I missed in the last kernel stats checkin.
cpu/checker/cpu.cc:
Allow the checker to disable its kernel stats.
cpu/cpu_exec_context.cc:
Allow CPUExecContext to be created without kernelStats.
cpu/cpu_exec_context.hh:
Allow CPUExecContext to be created without kernelStats. Default usage leaves kernelStats on.
