Dodji Seketeli 5b9f5efab2 PR25058 - Better support fn DIEs referring to symbols using DW_AT_ranges 
In the previous commit 2f7248f, we were just taking the first address
referred to by the DW_AT_ranges attribute as being the address of the
symbol of the function we are looking at.  But there can be cases
where this is not true, as explained at
https://sourceware.org/bugzilla/show_bug.cgi?id=25058#c7.

We really need to get the first address that represents an exported
and defined function symbol, which is pointed to by the DW_AT_ranges
attribute.

And this is what this patch does.

	* src/abg-dwarf-reader.cc
	(read_context::get_first_exported_fn_address_from_DW_AT_ranges):
	Rename read_context::get_first_address_from_DW_AT_ranges into
	this.  Walk through the addresses referred to by the DW_AT_ranges
	attribute until we find one that is for an exported function
	symbol, rather than just picking the first address of the set.
	(read_context::get_function_address): Adjust.

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
