[X86][SSE] combineExtractWithShuffle - extend extract(truncate(x),0) for any source vector size
As long as we can extract the lowest 128-bit subvector from the pre-truncated source vector, then we don't care what size it is.
The next stage will be to support non-zero extraction indices, as long as its still coming from the lowest 128-bit subvector.
