From: "Paul E. McKenney" <paul...@linux.vnet.ibm.com> Sometime problems can manifest themselves as unusually slow grace periods. This commit therefore prints the number of rcutorture updates during the test and the number per second. These statistics are harvested from the config.out and qemu-cmd files, and are silently omitted if these files are not available, as would be the case if there was a build failure or a boot-time hang.
