The local copy of bits.OnesCount64 was added for compatibility with Go

requires Go 1.12, so drop the local copy and use bits.OnesCount64.

Resolves a number of issues, except for the clen function being
unused on Linux, as that would require a larger refactor which
probably isn't strictly necessary.
