pdqsort vs qsort round 3

// Source Code: https://gist.github.com/qtxie/12c087db8a2c0c2d9fe0104af2f4236e
// compare Cell struct
// struct Cell {
//  int header;
//  int pading;
//  int value;
//  int pading2;
//  Cell(int x) : value(x) {}
//  bool operator<(const Cell& r) const
//  {
//      return value < r.value;
//  }
// };
// Disable Optimization when compling.
