Marco Costalba a87ea9846d Use bsfq asm instruction to count bits ... On 64 bit systems we can use bsfq instruction to count set bits in a bitboard. This is a patch for GCC and Intel compilers to take advantage of that and get a 2% speed up. Original patch from Heinz van Saanen, adapted to current tree by me. No functional change.
