GlobalOpt didn't know how to simulate InsertValueInst or ExtractValueInst. Optimizing these is pretty straightforward. N.B. This came up when looking at clang's IRGen for MS ABI member pointers; they are represented as aggregates. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@215184 91177308-0d34-0410-b5e6-96231b3b80d8
