Not enough try-catch in the pipeline

[ulysses4ever]

It seems that when type inference (used in is_stable_call) sometimes fails for some reason. More try-catch!

We should check if the approach works for @generated functions.

[ulysses4ever]

Generic mitigation for this kind of issue (failure in @code_typed) is in 709bbee.

We do have enough of try-catch inside module_stats as of 1b5263f3b6. The problem with @generated functions will be discussed on a separate issue.
