    analyzer: show program point in -Wanalyzer-too-complex
    
    I found this useful when debugging.
    
    gcc/analyzer/ChangeLog:
            * engine.cc (exploded_graph::get_or_create_node): Show the
            program point when issuing -Wanalyzer-too-complex due to hitting
            the per-program-point limit.
