Now that we've replaced the vinsertf128 intrinsics, do the same for their extract twins. This is very much like D8086 (checked in at r231794): We want to replace as much custom x86 shuffling via intrinsics as possible because pushing the code down the generic shuffle optimization path allows for better codegen and less complexity in LLVM. This is also the LLVM sibling to the cfe D8275 patch.
