There is a trade-off between robustness of check and accuracy of the
diagnostic: the previous version, which works on generation, was too
fragile and lead to false-positives. Now we check on state machine
generation. However, since we do not have PSI for call, we can only
report diagnostic on whole suspend function or suspend lambda.
Additionally, the state machine is generated on crossinline suspend
lambdas regeneration and thus we do not have the PSI for the lambda as
well!
