Look at first parm type and artificial-ness to detect static-ness

Browse Source 
* src/abg-dwarf-reader.cc (build_class_type_and_add_to_ir): To
	tell if a member function is static, look if the first parm is a
	pointer to the type of the enclosing class, and if it's
	artificial.  Don't bother trying to be smart by looking at the
	non-presence of DW_AT_object_pointer b/c that attribute wasn't
	emitted by GCC 4_4.
