Ahmed Bougacha d04f83361d [BasicAA] Add datalayouts to make some tests more useful. NFC.
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.
