I didn't notice any significant changes in the actual checks here; all of these tests already used FileCheck, so a script can batch update them in one shot. This commit is just to show the value of automating this process: We have uniform formatting as opposed to a mish-mash of check structure that changes based on individual prefs and the current fashion. This makes it simpler to update when we find a bug or make an enhancement. llvm-svn: 264457
