Closes #21877 * removes coverage of inlined nodes (as mentioned in the accompanying comment, those are impossible to represent in most cases) * adds coverage for Literals (ones directly in Apply are omitted) * removes coverage of `throw` contents * if apply node is tagged, we do not tag it's prefix, outside of other prefixing Apply's arguments (eg. when we tag `a+b+c` we do not redundantly tag `a+b`) * allows instrumenting synthetic method calls (like apply of a case After all of these changes the statements tagged are much more similar to Scala 2, let's look at the #21877 minimisation: * Scala 2: <img width="704" height="364" alt="Zrzut ekranu 2025-08-12 o 17 07 31" src="https://github.com/user-attachments/assets/f647dfa5-973e-424f-9818-483b7d01d550" /> <img width="740" height="379" alt="Zrzut ekranu 2025-08-12 o 17 07 46" src="https://github.com/user-attachments/assets/09eca1c0-a202-4e5e-b3e4-0947d9e8662d" /> * Scala 3: <img width="623" height="360" alt="Zrzut ekranu 2025-08-12 o 17 08 48" src="https://github.com/user-attachments/assets/efd5baaa-9f52-4ad6-9ba6-2f5bde42a470" /> <img width="638" height="428" alt="Zrzut ekranu 2025-08-12 o 17 08 55" src="https://github.com/user-attachments/assets/01ff6cc6-c348-47db-8ae5-d758ca0bf302" /> There are some differences still remaining, most notably the tagging the DefDefs and its default parameters, but I left them for now, as those seem more useful than harmful. BEcouse of those changed most of the .covergae files had to be regenerated, however I want through each and every diff to make sure that all of those changes there are expected. Additionally, this PR also fixes #21695 (issue with certain generated Block nodes not having assigned the correct type, causing later undefined errors). [Cherry-picked c535dbc]
