[Haskell-cafe] GHC vs GCC vs JHC

Here are jhc's timings for the same programs on my machine. gcc and ghc
both used -O3 and jhc had its full standard optimizations turned on.

./hs.out  5.12s user 0.07s system 96% cpu 5.380 total

./a.out  5.58s user 0.00s system 97% cpu 5.710 total

./try  31.11s user 0.00s system 96% cpu 32.200 total

As you can see, jhc shines at this example, actually beating gcc -O3. It
isn't too surprising, this is exactly the sort of haskell code that jhc
excels at.
