Comment (by xnyhps):

 I found #5218, which sounds like a nice solution for bytestrings because
 it gives the option to do different things with string and bytestring
 literals (part 2 of
 [https://ghc.haskell.org/trac/ghc/ticket/5218#comment:3 comment 3]). I can
 look at this at the same time.

 Alternatively, using the same heuristic as GCC would also be an option:
 align only ≥32 byte strings. (`genCCall` has a maximum length it will
 unroll, but I can't tell what that practically is on x86.)
