Dodji Seketeli 9136c6a639 Handle several virtual member functions having the same vtable offset 
In the DWARF for C++, it can happens that a virtual constructor leads
to several (up to 3) destructor functions that all have the same
vtable offset.  That vtable offset is the same as the offset of the
virtual destructor that the user actually defined in her source code.

This patch adds a map data structure to the private data of
class_decl.  That map associates a vtable offset X to a vector of
virtual member functions that have the same vtable offset X.

That new map is populated whenever a virtual member function is added
to the class.

	* include/abg-ir.h (class_or_union::virtual_mem_fn_map_type):
	Define new typedef.
	(class_decl::get_virtual_mem_fns_map): Declare new accessor.
	* src/abg-ir.cc (class_decl::priv::virtual_mem_fns_map_): New data
	member.
	(class_decl::get_virtual_mem_fns_map): Define new accessor.
	(fixup_virtual_member_function): Populate the new virtual member
	functions map.
	(class_decl::on_canonical_type_set): Sort the virtual member
	function vectors stored in the new virtual member functions map.
	(class_decl::add_member_function): Call
	set_member_function_is_virtual *after* calling
	set_member_function_vtable_offset because the former updates the
	virtual function map, so it needs the vtable offset.
	* src/abg-dwarf-reader.cc (finish_member_function_reading):
	Likewise.
	* src/abg-reader.cc (build_class_decl): Likewise.

README 

This is the Application Binary Interface Generic Analysis and
Instrumentation Library.

It aims at constructing, manipulating, serializing and de-serializing
ABI-relevant artifacts.

The set of artifacts that we are intersted is made of quantities like
types, variable, fonctions and declarations of a given library or
program.  For a given library or program this set of quantities is
called an ABI corpus.

This library aims at (among other things) providing a way to compare
two ABI Corpora (apparently the plural of corpus is copora, heh,
that's cool), provide detailed information about their differences,
and help build tools to infer interesting conclusions about these
differences.

You are welcome to contribute to this project after reading the files
CONTRIBUTING and COMMIT-LOG-GUIDELINES files in the source tree.

Communicating with the maintainers of this project -- including
sending patches to be include to the source code -- happens via email
at libabigail@sourceware.org.
