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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@264457 91177308-0d34-0410-b5e6-96231b3b80d8
