Thanks to help from Nadav and Hal, I have a more reasonable (and even correct!) approach. This specifically penalizes the insertelement and extractelement operations for the performance hit that will occur on PowerPC processors. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174725 91177308-0d34-0410-b5e6-96231b3b80d8
