Comment (by dfeuer):

 Is there a benefit to baking it in as a primop rather than making it an
 FFI function in `base` or even `ghc-prim`? If not, I don't see the point.
 Personally, I suspect that there is not ''yet'' a benefit, but that there
 might be one in the future. In particular, if we ever have sufficient
 support for vector registers, we might get a small speed boost by
 implementing `memchr#` ourselves and inlining it.
