Hi Patrick,

In case of a larger switch statement with case values that cannot be 
combined, you could end up with very large number of ASSERT_EXPRs in the 
default basic block. I am not sure if this would have any impact on 
compile time/memory usage? If that is the case you might want to punt at 
some length?

Thanks,
Kugan
