      define builtin clz/ctz calls MSVC equivalents · e2d329fb
      Steve Lhomme authored
      __builtin_ctz:
      Returns the number of trailing 0-bits in x, starting at the least significant
      bit position. If x is 0, the result is undefined.
      
      _BitScanForward:
      Search the mask data from least significant bit (LSB) to the most significant
      bit (MSB) for a set bit (1). If a set bit is found, the bit position of the
      first set bit found is returned in the first parameter. If no set bit is found,
      0 is returned; otherwise, 1 is returned.
      
      __builtin_clz:
      Returns the number of leading 0-bits in x, starting at the most significant
      bit position. If x is 0, the result is undefined.
      
      _BitScanReverse:
      Search the mask data from most significant bit (MSB) to least significant bit
      (LSB) for a set bit (1). Returns Nonzero if Index was set, or 0 if no set bits
      were found. Index is loaded with the bit position of the first set bit (1) found.
