RFR(XS) (11) 8197447 : LogCompilation throws "couldn't find bytecode"

[Eric Caspole]

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
