[LLVMdev] Folding an insertelt chain
Hello, I've added a little combining operation in DAGCombiner to fold a chain of insertelt nodes if that chain is proved to fully overwrite the very first source vector. In which case, I supposed a build_vector is better. It seems to be safe but I don't know if it is correctly implemented or if it is already done somewhere else. Please find attached the patch. Regards, Ivan
