Detailed Description
When a region containing undefined value or '0' value is passed as an argument in a call, marks the call as interesting.
As a result, BugReporter will not prune the path through the function even if the region's contents are not modified/accessed by the call.

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.
