Some optimization for fun

Hi all!

I stumbled over a guy looking at Squeak performance and decided to see if
I could optimize his particular problem. I ended up writing a highly
optimized version of #printString in class SmallInteger.

Don't know if it is of general interest but it does give a speedup of
sending #printString to SmallIntegers around 4x I think.

See my comment here:

Hi Göran,

it's great. Would you please write tests and send a mail so that your
enhancement get a chance to be included?

Ok, ended up tweaking a bit more and added my last version on Mantis:

Time millisecondsToRun: [1 to: 20000 do: [:i | m := i printString]]

run in 212ms (3.9-7067) and 37 ms (with 2.cs)

Great work! .. Subbu
