@reames let's continue the discussion here. What specific bits with the optimizer does this break? I'm not too familiar with SVEC. Prior to this, one thing I tried was instead just doing `Ops.push_back(GA)` and `getSCEV(GA)` but those seemed to result in infinite recursions last I checked probably because there's another pass attempting to resolve aliases.
