v8f32 shuffles in the new vector shuffle lowering code. This is very cheap to do and makes it much more clear that anything more expensive but overlapping with this lowering should be selected afterward (for example using AVX2's VPERMPS). However, no functionality changed here as without this code we would fall through to create no-op shuffles of each input and a blend. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@218209 91177308-0d34-0410-b5e6-96231b3b80d8
