I'm actually pretty sure that it never worked.

I'll take your word on that.

The think in and ideal world we would a:

* Make it work correctly FLAC__BYTES_PER_WORD == 8 and compare the performance
  with FLAC__BYTES_PER_WORD == 4.
* If there is an statistically measurable performance, keep it, otherwise
  remove the FLAC__BYTES_PER_WORD == 8 code all together.

Since you seem to think there little to be gainned, maybe its better to
just remove the FLAC__BYTES_PER_WORD == 8 code now.
