Thanks for rebasing.

I don't think there's any need to mention Intel in each of the
following comments:

+# Check for Intel AVX512 intrinsics to do POPCNT calculations.

+# Newer Intel processors can use AVX-512 POPCNT Capabilities (01/30/2024)

AMD's Zen4 also has AVX512, so it's misleading to indicate it's an
Intel only instruction.  Also, writing the date isn't necessary as we
have "git blame"
