[GCC-XML]Structs generated by gcc

[wyf at fudan.edu.cn]

Hello, Brad
  There are some structs generated by gcc, for example:
   <Struct id="_7" name="__vmi_class_type_info_pseudo1" context="_1" mangled="29__vmi_class_type_info_pseudo1" location="f0:4" file="f0" line="4" members="_17 _18 _19 _20" bases="" /> 

  <Struct id="_12" name="__class_type_info_pseudo" context="_1" mangled="24__class_type_info_pseudo" location="f1:0" file="f1" line="0" members="" bases="" /> 
   
   Would you please add an "artificial" attribute for this kind of struct/class? Otherwise I can't distinguish a struct/class written by user or generated by gcc.

   Thanks
