Hi - could anyone review this patch? This fix is handy for me where I am 
using the tool a lot lately.
Thanks,
Eric

Hi everybody,

Please review this small change to the LogCompilation tool, where it did 
not support processing the unstable_fused_if uncommon trap which would 
take the place of the first unstable_if in the original code.

I would like to add a test case for this but I am not sure what code 
sequence would be sure to get this optimization, and also not result in 
a giant log (where I originally found this problem while debugging an 
unrelated problem). Open to suggestions.

Thanks,

Eric
