In the recent discussion [1], it was noticed that find_next_bit() functions may be improved by adding wrappers around common __find_next_bit().
I tried that trick; and although it doesn't affect performance significantly, as reported by find_bit_benchmark, there's ~2.5K decrease in image size.
find_first_bit() is reworked accordingly.
