The original costs stopped at SSE42, I've added conservative estimates for everything down to SSE1/SSE2 and moved some of the SSE42 costs to SSE41 (really only the addition of PCMPGT makes any difference). I've also added missing vXi8 costs (we use PHMINPOSUW for i8/i16 for scarily quick results) and 256-bit vector costs for AVX1. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@360528 91177308-0d34-0410-b5e6-96231b3b80d8
