Indeed.  However, the purpose of this code is to outperform the equally
well optimised version in C and compiled with GCC or Clang.  That's also
the sole reason why I used TH to precompute a value that should never
have been noticable in the first place.  The code was written for GHC
7.6.  More recent versions might no longer require TH to outperform
GCC/Clang.
