instructions in order to avoid inserting new ones. However, if the cast instruction is the SCEVExpander's InsertPt, this causes subsequently emitted instructions to be inserted near the cast, and not at the location of the original insert point. Fix this by adjusting the insert point in such cases. This fixes PR4009. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69808 91177308-0d34-0410-b5e6-96231b3b80d8
