A given diff node for a type can be hung off of several contexts: a
function parameter type node, another type diff node, etc. For that
reason, a type diff node should not have a parent node. Thus, it's
should be the job of the context containing the type diff node to
propagate its categories to the context nodes. This actually fixes a bug
about category propagation.

(class_diff::report): Adjust.
* src/abg-corpus.cc (symtab_build_visitor_type::visit): Remove the
overload that takes a class_decl::data_member*. Adjust the
overload that takes a var_decl to recognize (static) data members.

(is_data_member): New function definition.
({get,set}_data_member_{offset,is_laid_out}): Define new
accessors.
(var_decl::set_scope): Define new member function. Make this set
a dm_context_rel as the context relationship.

member relationship.

* include/abg-comparison.h (class base_diff): New.
* include/abg-ir.h (function_decl::get_first_non_implicit_parm):
New member function.
(function_type::get_first_non_implicit_parm): Likewise.
* src/abg-comparison.cc (base_has_changed): Change parm to take
class_decl::base_spec_sptr.
(class_diff::ensure_lookup_tables_populated): Compare the base
specs not just the base classes.
(class_diff::report): Adjust. Report sub-type changes in the
member functions.
(base_diff::*): Define member functions.
(compute_diff): Define an overload for base_diff_sptr.
* src/abg-hash.cc ({function_type,
method_type}:#️⃣:operator()): Do not hash the implicit parm of
member functions.
(class_decl:#️⃣:operator()): Do not hash member types.
* src/abg-ir.cc (decl_base::decl_base): Initialize the
hashing_started_ member that got moved here from class_decl.
(decl_base::get_hash): Do not set the hash if it's being set b/c
we are in a class_decl.
(decl_base::operator==) Do not compare hashes for now. Two decls
can have different hashes and compare equal; think about an
incomplete type foo, that compares equal with a complete foo.
Their hashes will be different though. So for now, just avoid
comparing these.
(compare_function_types): Avoid comparing the implicit parameter
for member functions.
({function, method}_type::get_first_non_implicit_parm): New
definition.
* tests/data/test-read-write/test20.xml: Update.

* src/abg-dwarf-reader.cc (build_class_type_and_add_to_ir): Do not
declare classes before defining them because both the declaration
and the definition now compare equal.

* tests/data/test-read-write/test20.xml: Likewise.
