FWIW, changing:

          if (!STMT_VINFO_GROUPED_ACCESS (dr_stmt))
            continue;

to:

          if (!STMT_VINFO_GROUPED_ACCESS (dr_stmt))
            {
              partition.layout = -1;
              continue;
            }

in start_choosing_layouts fixes it for me.  We can then choose layout 1 for the
splat.

I think these conditions were carried over from the old code.  Without checking
further, I'm not 100% sure what effect relaxing them would have :)
