[Haskell-cafe] speed: ghc vs gcc vs jhc

Don't forget jhc:

on my machine (with 'print' equivalent added to C one to be fair, and
10^9 changed to 1000*1000*1000 just like the C one)

ghc: (-O2)
time ./foo
./foo  2.26s user 0.00s system 99% cpu 2.273 total

time ./a.out
./a.out  0.34s user 0.00s system 99% cpu 0.341 total

time ./hs.out
./hs.out  0.33s user 0.00s system 96% cpu 0.347 total

Yay! it is good to see my goal of C-equivalent performance starting to
come true :)
