Sander de Smalen 6709b193ea [SelectionDAG] Make WidenVecRes_EXTRACT_SUBVECTOR work for scalable vectors. 
The legalizer handles this by breaking up an EXTRACT_SUBVECTOR into
smaller parts, and combines those together, padding the result with
UNDEF vectors, e.g.

  nxv6i64 extract_subvector(nxv12i64, 6)
  <->
  nxv8i64 concat(
    nxv2i64 extract_subvector(nxv16i64, 6)
    nxv2i64 extract_subvector(nxv16i64, 8)
    nxv2i64 extract_subvector(nxv16i64, 10)
    nxv2i64 undef)
