Mostly the latter. We think it accomplishes it more easily and  
effectively than using the DW_TAG_inlined_subroutine. To be  
completely honest, we were DWARF-2 based when we cooked this up, so  
DW_AT_call_file, etc., were not there at the time.

It's also advantageous for us because we generate line number tables  
with just a minimal skeleton of DIEs for the purposes of profiling,  
even when debug is turned off.
