} Isn't this more efficient?
} n = (x>>32) | (x<<32);
} n = ((n & 0x0000ffff0000ffffLL)<<16) | (n & 0xffff0000ffff0000LL)>>16;
} n = ((n & 0x00ff00ff00ff00ffLL)<<8) | (n & 0xff00ff00ff00ff00LL)>>8;
}
} 6 shift
} 4 and
} 3 or

Plus 3 assigns...but they may get optimized out. :)
} instead of
}
} 8 shift
} 8 and
} 7 or
