Yes, absolutely agree. Actually, the testcase was a *manually simplified* version of bugpoint's output - bugpoint's simplified output had 230 lines in the testcase! 
Clearly, the manual simplification (75 lines) could still be improved :)

As an aside I think bugpoint needs improvement around invokes and landing blocks (unless there's some specific option to use here other than -compile-custom).
