Fix BasicAA's recursion detection so that it doesn't pessimize queries in the case of a DAG, where a query reaches a node visited earlier, but it's not on a cycle. This avoids MayAlias results in cases where BasicAA is expected to return MustAlias or PartialAlias in order to protect TBAA. llvm-svn: 132609
