The DWARF has the same nesting information as the source code; the 
consumer can use the same algorithm as the compiler.  I don't think we 
want to encode standard lookup rules in the debugging information; 
better to put that in one place in the debugger rather expand the 
debugging information for every occurrence of a using-declaration.
