[PATCH] D41794: [X86] Improve AVX1 shuffle lowering for v8f32 shuffles where the low half comes from V1 and the high half comes from V2 and the halves do the same operation

Looks like X86ISD::SHUF128 isn't recognized as a target shuffle. That explains some of the regressions here. I'll submit a separate patch for that and we can rebase this one.
