Check that (most) positions are non-overlapping.
Check that children of a node have non-overlapping positions and that positions
of successive children are monotonically increasing.
This holds currently except for 3 exceptions:
- Trees coming from Java as the Java parser also does desugarings which copy trees.
- Functions coming from wildcard expressions
- Interpolated strings
We'll see whether we can do something about the latter two.
