* stabs.c (parse_stab_range_type): Handle 4 and 8 byte signed 

integers with real upper bounds.  Handle a lower bound one larger
 	than the upper bound as a signed integer.  Handle 8 byte signed
	integers.
	(stab_demangle_template): Optionally return the demangled name of
	the template.
	(stab_demangle_qualified): Treat a template name as a tagged
	type.
	(stab_demangle_fund_type): Likewise.
