Chandler Carruth c51f300513 [PM/AA] Completely remove the AliasAnalysis::copyValue interface. ... No in-tree alias analysis used this facility, and it was not called in any particularly rigorous way, so it seems unlikely to be correct. Note that one of the only stateful AA implementations in-tree, GlobalsModRef is completely broken currently (and any AA passes like it are equally broken) because Module AA passes are not effectively invalidated when a function pass that fails to update the AA stack runs. Ultimately, it doesn't seem like we know how we want to build stateful AA, and until then trying to support and maintain correctness for an untested API is essentially impossible. To that end, I'm planning to rip out all of the update API. It can return if and when we need it and know how to build it on top of the new pass manager and as part of *tested* stateful AA implementations in the tree.
