My opinion is that I've never had bzip find a bug that some other
spec test hasn't. I think 20 hours is way too long for a regression
test. We should either shrink the input size or just not have it.

people feel about this? bzip2 in x86 on O3 takes more than 20 hours to
run. Should that be part of the regressions or not? I have it ready to
go if that's acceptable, but to me it seems too long.

updates out for review. I'm adding new regressions here, though, and I
think people may be interested in the run time, especially for bzip2. I
think it was about 20+ hours on opt on a big machine from HP. This may
be trimmed down if/when performance bottlenecks get fixed since O3 will
have to do less work, but cutting it in half is still a long, long time
for a regression. I notice that the number of ticks for the benchmarks
that are in common with Alpha is about 4 times higher, suggesting a
performance bug of some sort (I doubt x86 gcc is 4X worse).
