As per "Intel Architecture Instruction Set Extensions and Future Features Programming Reference" manual , vector popcount instruction will be supported in future Intel ISA. I have updated the superword vectorizer to take advantage of this instruction. I have tested with Intel SDE  to confirm encoding and semantics are correctly implemented. Please take a look and let me know if you have any questions or comments.
