If there aren't many bytes to process, the function call overhead of the optimized implementation isn't worth taking, so instead we inline a loop that consults pg_number_of_ones in that case. If there are many bytes to process, we accept the function call overhead because the optimized versions are likely to be faster. The threshold at which we use the optimized implementation is set to the smallest amount of data required to use special popcount instructions.
