vinsertf128 $1 + vpermilps $0, remove the old code that used to first do the splat in a 128-bit vector and then insert it into a larger one. This is better because the handling code gets simpler and also makes a better room for the upcoming vbroadcast! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137807 91177308-0d34-0410-b5e6-96231b3b80d8
