    analyzer: fix sm_state_map::print
    
    In 10fc42a8396072912e9d9d940fba25950b3fdfc5 I converted state_t from
    unsigned to const state *, but missed this comparison against 0.
    
    gcc/analyzer/ChangeLog:
            * program-state.cc (sm_state_map::print): Update check
            for m_global_state being the start state.
