Actually, just after sending the update I realized that inputs with mixed vector sizes are supported because `vector.shuffle`, unlike the llvm counterpart, supports vector inputs with different sizes... I think they are poorly lowered to LLVM (I think using insert/extract ops) but from the PoV of this transformation it would be as simple as removing the bail out check to have them working :)
