    WARNING! This implementation doesn't strictly follow the contract from DirectBitSet interface. For the sake of atomicity this implementation couldn't find and flip the range crossing native word boundary, e. g. bits from 55 to 75 (boundary is 64).

    fromIndex - the index to start checking from (inclusive)
    
    numberOfBits - how many continuous clear bits to search and set
    
    Returns:
    
    the index of the first bit in the found range of clear bits, or -1 if there is no such range
    
    Throws:
    
    IllegalArgumentException - if numberOfBits is out of range 0 < numberOfBits && numberOfBits <= 64
