The comment is misleading here.  DOM is simply constant propagating in
this case, not threading jumps.

Alternately, you could just scan for 'return 4' in the .optimized dump. 
Or are you trying to test something more specific?

Also, there's only one 'l' in eliminate.

Otherwise, the tests look OK.  Thanks.

Another category of tests that would be interesting to add are those
that we should be getting right, but aren't.
