Benchmarking harnesses for a more modern nofib?

[Carter Schonwald]

The cause of the initial blowup was adding the vector test suite to the
normal cabal file, in both 0O and O2 forms.  This was done so that fusion
rules based bugs wouldn't lie in hiding for years.

It sounds like the issues that resulted in built blowup are fixed in 8.0.
My guess is it's a combination of some type class coercion / equality
manipulation getting better plus other improvements in 8.0, both.
