Count bits pop(x) algorithm, table lookup method
From the book "Hacker's delight" by Henry S. Warren, Jr., page 71
The algorithm precomputes pop(x) for x in range 0 to 255 and stores it
into a lookup table.

We cross-check it with the obvious method of counting bits:
for (s = i = 0; i < BW; i++)
  if (x & (1 << i))
    s++;
