Fix a bug in getSCEVAtScope w.r.t. non-canonical loops The issue is that if we have a loop with multiple predecessors outside the loop, the code was expecting to merge them and only return if equal, but instead returned the first one seen. I have no idea if this actually tripped anywhere. I noticed it by accident when reading the code and have no idea how to go about constructing a test case. llvm-svn: 363112
