[PATCH] D24441: [AA] Add the notion of target-specific alias analyses.

[Hal Finkel via llvm-commits]

hfinkel added a comment.

It seems somewhat unfortunate to have both ExternalAAWrapperPass and TargetSpecificAAWrapperPass. It also seems unfortunate that we can only ever have one external AA provider. What if we let ExternalAAWrapperPass contain an array of callbacks and let the target add to that array?
