This test, here and in value_format, should be factored out into a 
separate function with a comment explaining why you check 
dwarf_split_debug_info.

In general there's a lot of code duplication between the existing ranges 
support and the new rnglist support; even the new vector is a superset 
of the old one.  Why duplicate the code rather than modify it?
