Commit ID 94ecdef8ac7855e7a44efd7890c7e8f8d5819397
Author Marco Costalba

Micro-optimize pop_lsb() for 64bit case On Intel, perhaps due to 'lea' instruction this way of zeroing the lsb of *b seems faster than a shift+negate. On perft (where any speed difference is magnified) I got a 6% speed up on my Intel i5 64bit. Suggested by Hongzhi Cheng. No functional change.
