    analyzer: fix build error with clang (PR 93543)

    https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=243681 reports a build
    failure with clang 9.0.1:

    gcc/analyzer/engine.cc:2971:13: error:
          reinterpret_cast from 'nullptr_t' to 'function *' is not allowed
      v.m_fun = reinterpret_cast<function *> (NULL);
                ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    engine.cc:2983:21: error:
          reinterpret_cast from 'nullptr_t' to 'function *' is not allowed
      return v.m_fun == reinterpret_cast<function *> (NULL);
                        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    The casts appears to be unnecessary; eliminate them.

    gcc/analyzer/ChangeLog:
        PR analyzer/93543
        * engine.cc (pod_hash_traits<function_call_string>::mark_empty):
        Eliminate reinterpret_cast.
        (pod_hash_traits<function_call_string>::is_empty): Likewise.
