Here's an excerpt from the code we already have for interleave on fixed vectors. Need to see why it doesn't trigger here.

  // Detect an interleave shuffle and lower to                                   
  // (vmaccu.vx (vwaddu.vx lohalf(V1), lohalf(V2)), lohalf(V2), (2^eltbits - 1)) 
  bool SwapSources;                                                              
  if (isInterleaveShuffle(Mask, VT, SwapSources, Subtarget)) {
