Comment (by hvr):

 Fwiw, I can see the appeal to abstract over the basic low-level ISO C99
 memory primitives (`memcmp`, `memchr`, `memcpy`, `memset` etc, some of
 which may have a LLVM primitive op counterpart), which makes it easier for
 projects like ghcjs, eta, or the upcoming ghc/wasm if `ghc-prim` already
 provides the primitives in a single central place, than having to patch N
 packages which FFI call themselves.

 It seems to me, that `memchr(3)` may be the only one left from the ISO C99
 set of `mem*` family of functions operating on byte arrays we haven't yet
 wrapped.
