Some notes:
- If there are related tests (e.g. it's for the same issue), they are moved along with it.
- Moved try-block.rs to the `try-block` dir.
- Moved tup.rs to the `tuple` dir.
- Moved some tests that classified as consts to the `statics` dir, as it seems they have statics actually.
- Skipped backtrace-debuginfo.rs because I think classifui overrates their helper macros.
