For this program they produce the same checksum since all of the bitboards have
a population of one (msb == lsb, in this test).

It probably doesn't matter for a lot of bitboard chess programs. For most, any
bit will do. For some it matters. I know for some of the filler stuff I've
written I had to make sure I used a lsb or msb. I think both will be
approximately the same speed, or very close.
