Sanjay Patel 5a5e82c5f0 [x86] narrow a shuffle that doesn't use or set any high elements ... This isn't the final fix for our reduction/horizontal codegen, but it takes care of a lot of the problems. After we narrow the shuffle, existing combines for insert/extract and binops kick in, and we end up with cheaper 128-bit ops. The avg and mul reduction tests show an existing shuffle lowering hole for AVX2/AVX512. I think in its most minimal form this is: https://bugs.llvm.org/show_bug.cgi?id=40434 ...but we might need multiple fixes to get it right.
