Dodji Seketeli 5d24cf87d7 Support DW_AT_count DWARF attribute 
Libabigail's DWARF reader does not support the DW_AT_count attribute
used to specify the number of elements in an array subrange.  Rather,
it uses the DW_AT_lower_bound and DW_AT_upper_bound attributes that
are emitted by GCC.  Recent versions of Clang, on the other hand, use
the DW_AT_count attribute.

This patch adds support for the DW_AT_count attribute too.

	* src/abg-dwarf-reader.cc (get_default_array_lower_bound): Define
	new static function.
	(build_array_type): Support the DW_AT_count attribute.
	* tests/data/test-diff-dwarf/test35-pr19173-libfoo-long-clang.so:
	New test binary input.
	* tests/data/test-diff-dwarf/test35-pr19173-libfoo-long-clang2.so: Likewise.
	* tests/data/test-diff-dwarf/test35-pr19173-libfoo-long-clang-report-0.txt:
	New test reference output.
	* tests/data/test-diff-dwarf/test35-pr19173-libfoo-long-gcc.so:
	New test binary input.
	* tests/data/test-diff-dwarf/test35-pr19173-libfoo-long-gcc2.so:
	New test binary input.
	* tests/data/test-diff-dwarf/test35-pr19173-libfoo-long-gcc-report-0.txt:
	New test reference output.
	* tests/data/test-diff-dwarf/test35-pr19173-libfoo-long.c: Source
	code for the binaries above.
	* tests/data/Makefile.am: Add the new test material to the build
	system.
	* tests/test-diff-dwarf.cc (in_out_specs): Add the new test inputs
	to the harness.

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.
