compileable c++ test case and dwarf dump

For strong typed enum, there is no  type information:

#include <iostream>

enum UI: unsigned int
{
        None = 0,
        Single = 1,
        Multiple = 0xFFFF0000U
};

 <1><26aa>: Abbrev Number: 69 (DW_TAG_enumeration_type)
     DW_AT_name        : UI
     DW_AT_byte_size   : 4
     DW_AT_decl_file   : 1
     DW_AT_decl_line   : 3
     DW_AT_sibling     : <26cc>

  Should have a DW_AT_type : <unsigned int type> under DW_TAG_enumeration_type
