Implement in VectorCombine an equivalate to shrinkSplatShuffle from InstCombineCasts.cpp that is cost model aware.
`castop(shuffle(X, undef/poison, splatMask)) -> shuffle(castop(X), undef/poison, splatMask)`
This is searching for the opposite transformation from VectorCombine::foldShuffleOfCastops, which pushes casting operations to happen later.
