Initial support for DW_TAG_partial_unit
* src/abg-dwarf-reader.cc (read_context::cur_tu_die_): New member.
(read_context::read_context): Initialize the new member.
(read_context::cur_tu_die): New accessors.
(find_last_import_unit_point_before_die): New static function.
(get_parent_die): Take a logical current die offset parameter. If
the die we want the parent for is a partial unit, then find the
last DW_TAG_imported_unit that imports that partial unit before
the logical current die and return the parent of that
DW_TAG_imported_unit die.
(get_scope_for_die): Take a logical current die offset parameter.
Adjust.
(build_translation_unit_and_add_to_ir): Set/unset the current
translation unit DIE in the context. Adjust.
(build_namespace_decl_and_add_to_ir)
(build_class_type_and_add_to_ir, build_qualified_type)
(build_pointer_type_def, build_reference_type, build_typedef_type)
(build_var_decl, build_function_decl, build_ir_node_from_die):
Take a logical current die offset parameter. Adjust.
(build_corpus): Accept that we can have DIE that are not
DW_TAG_compile_unit at the top level, because, well, we can now
have DW_TAG_partial_unit too.
* tests/data/test-read-dwarf/test2-{0,1}.cc: New test source
files.
* tests/data/test-read-dwarf/test2.h: Likewise.
* tests/data/test-read-dwarf/test2.so: New input binary to read.
* tests/data/test-read-dwarf/test2.so.abi: New reference test to
compare against.
* tests/test-read-dwarf.cc: Adjust to launch the new test.
