Log:
  If function die_name() finds a DIE without a name, set its name to
  "__anon__". This hack is used to workaround a issue that compilers
  like GCC could generate DW_TAG_base_type DIE without a name.
  
  Note that we didn't need this before because the old libdwarf
  internally set all the unnamed DIE's name to "__anon__".
