When target cost information is available, compute explicit costs of inserting and extracting values from vectors. At this point, all costs are estimated using the target information, and the chain-depth heuristic is not needed. As a result, it is now, by default, disabled when using target costs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167256 91177308-0d34-0410-b5e6-96231b3b80d8
