Fixes PR22462: two of the tests have regressed for a while, but were using CHECK-NOT to match "May:". The actual output was changed to "MayAlias:" at some point, which made the tests useless. Two others return MayAlias only because of a lack of analysis; BasicAA returns PartialAlias in those cases, when a datalayout is present. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@228346 91177308-0d34-0410-b5e6-96231b3b80d8
