Return a diagnostic piece which should be associated with the given node.

Note that this function does not get run on the very last node of the report, as the PathDiagnosticPiece associated with the last node should be unique. Use getEndPath to customize the note associated with the report end instead.

The last parameter can be used to register a new visitor with the given BugReport while processing a node.
