Dodji Seketeli 6f00afe353 Fix regression on the support for alternate debug info files ...

My commit "5a8c000 Bug 19355 - Libabigail slow on r300_dri.so"
introduced a faster way of getting the logical parent of a DIE, when
one of its ancestor DIEs has been imported into a the current
translation unit.

But then that commit broke the support for alternate debug info
files.  Oops.

This commit brings back the support for alternate debug info files.

	* src/abg-dwarf-reader.cc
	(imported_unit_point::imported_unit_from_alt_di): New data member.
	(imported_unit_point::imported_unit_point): Adjust.
	(read_context::alt_tu_die_imported_unit_points_map_): New data
	member.
	(read_context::alt_tu_die_imported_unit_points_map): New accessor.
	(die_die_attribute): Remove the overload which doesn't say if the
	resulting DIE comes from alternate debug info.
	(build_die_parent_relations_under): Take a new flag which says if
	we are building the relations about DIEs in the alternate debug
	info section or not.  Use that flag to know if the imported unit
	trace we are building is for an alternate debug info file or not.
	(build_die_parent_maps): Build two different imported unit point
	trace vectors: one for the main debug info file, and another one
	for the alternate debug info file.
	(find_import_unit_point_between_dies): Take a flag that says if
	the beginning of the search is a DIE in the alternate debug info
	file or not.  Use it to know if we should use the import point
	trace vectors from alternate debug info or from the main debug
	info file.  When the import point trace vector is empty, return
	immediatly.
	(get_parent_die): If the parent DIE is a DW_TAG_partial_unit which
	hasn't been imported into this TU, then assume the logical parent
	is the DIE for the current translation unit.
	* tests/data/test-diff-pkg/tbb-4.1-9.20130314.fc22.x86_64--tbb-4.3-3.20141204.fc23.x86_64-report-0.txt:
	Reference test output.
	* tests/data/test-diff-pkg/tbb-4.1-9.20130314.fc22.x86_64.rpm: New
	input test rpm.
	* tests/data/test-diff-pkg/tbb-4.3-3.20141204.fc23.x86_64.rpm:
	Likewise.
	* tests/data/test-diff-pkg/tbb-debuginfo-4.1-9.20130314.fc22.x86_64.rpm:
	Likewise.
	* tests/data/test-diff-pkg/tbb-debuginfo-4.3-3.20141204.fc23.x86_64.rpm:
	Likewise.
	* tests/data/Makefile.am: Add the new test materials to the source
	distribution.
	* tests/test-diff-pkg.cc (int_out_specs): Add the new rpms to the
	list of rpms to test against.
