Simon Pilgrim 200d59f918 [X86][SSE] lowerV16I8Shuffle - tryToWidenViaDuplication - undef unpack args ...

tryToWidenViaDuplication lowers using the shuffle_v8i16(unpack_v16i8(shuffle_v8i16(x),shuffle_v8i16(x))) pattern, but the unpack only needs the even/odd 16i8 args if the original v16i8 shuffle mask references the even/odd elements - which isn't true for many extension style shuffles.
