Avoid infinite recursion due to the loop hash parameter -> hash template -> hash parameter. (template_decl:#️⃣:operator()) Define this here, now that it's declared in abg-ir.h. Also, avoid infinite recursion here; this is complementary to what is done in the hashing for template_parameter.

Also, not that this constructor now takes the enclosing template decl. (class non_type_tparameter::priv): Define new type.

Initial support for function suppressions
* include/abg-comparison.h (enum visiting_kind): Change the
meaning of this. It was to determine if traversal was to be done
in a pre or post manner. But with the recent addition of
diff_node_visitor::visit_{begin,end}() notifiers, the pre/post
handling is taken care of in a different way. So now the meaning
of this enum is changed to handle whether diff node children
should be visited or not. So the enumerators are now
DEFAULT_VISITING_KIND, and SKIP_CHILDREN_VISITING_KIND. And it's
a bit-field.
(operator{&,~}): Declare more bit manipulation operators for the
enum visiting_kind.
(function_suppression_sptr, function_suppressions_type): New
typedefs.
(function_suppression, function_suppression::parameter_spec):
Declare new types.
(read_function_suppressions): Declare new function.
(diff_node_visitor::diff_node_visitor): Adjust for the enum
visiting_kind change. Value-initialize the visiting_kind_ data
member.
* src/abg-comparison.cc (operator{&,~}): Define these operators
for enum visiting_kind.
(read_type_suppressions): Forward declare this static function.
(read_function_suppression, read_parameter_spec_from_string):
Define new static functions.
(read_suppressions): Update to read function suppressions too,
using the new read_function_suppression function above.
(class function_suppression::parameter_spec::priv): Define new
type.
(function_suppression::parameter_spec::*): Define the member
functions of the new function_suppression::parameter_spec type.
(class function_suppression::priv): Define new type.
(function_suppression::*): Define the member functions of the new
function_suppression type.
(diff::traverse): There is no more {PRE,POST}_VISITING_KIND
enumerator. So nuke the code that was dealing with it.
(redundancy_marking_visitor::skip_children_nodes_): New data
member flag.
(redundancy_marking_visitor::visit_begin): If the current diff
node is not be reported (is filtered out), do not bother visit its
children nodes for the purpose of marking redundant nodes. So use
the new skip_children_nodes_ flag above to know we are in that case.
(redundancy_marking_visitor::visit_end): Unset the new
skip_children_nodes_ flag above when appropriate.
* include/abg-fwd.h (is_function_decl): Declare new function.
* include/abg-ir.h
(function_type::get_parm_at_index_from_first_non_implicit_parm):
Declare new member function.

Define new member function.

visiting_kind change. No need to set it for filters anymore

function suppression addition.

Fix reading several clones of the same member function from DWARF

function to class class_decl::method_decl.
* src/abg-dwarf-reader.cc (finish_member_function_reading): Split
this out from build_class_type_and_add_to_ir. Use the new setters
for member functions properties introduced above.
(build_class_type_and_add_to_ir): Factorize the creation of member
function by using build_ir_node_from_die. Once that function has
created the member function in a rather generic way, use the new
finish_member_function_reading to set the remaining specific
properties for member functions.
(build_function_decl): When called to read additional properties
of a function_decl, allow this to read and update the elf symbol
properties too. This is useful for building a clone of a function
that already has an elf symbol.
(build_ir_node_from_die): When building a function decl, consider
the case of a DIE that has both DW_AT_specification and
DW_AT_abstract_origin set. That is, DW_AT_abstract_origin is set,
and the origin has DW_AT_specification set. This is basically a
clone of a function that implements an interface (this happens for
destructors, for instance). In this case, really do the cloning
of the interface implementation. If the cloned function happens
to be member function, use finish_member_function_reading to read
the properties relevant to its method-ness.
* src/abg-ir.cc (set_member_function_is_ctor)

(struct virtual_member_function_less_than): New functor.
(class_decl::add_member_function): Keep virtual member functions
vector sorted.
* data/test-read-dwarf/test1.abi: Adjust. Now, both the
cdtor specification and all the clones that implements the
different are emitted.
* data/test-read-dwarf/test2.so.abi: Likewise.

alternate debug info section too. We shouldn't have to do all

though, we should conditionally use that instead.

Don't share types across TUs when DW_TAG_partial_unit are involved
* src/abg-dwarf-reader.cc (build_translation_unit_and_add_to_ir): Clear the part of the context that needs to be per TU. (build_ir_node_from_die): Assert that this should not be called for partial and imported unit because for now our practical assumption is that DIEs under partial unit are lazily read only when referenced by DIEs that are under DW_TAG_compile_unit. * tests/Makefile.am: Add the new test files to the build system. * tests/data/test-read-dwarf/test2.so.abi: Fix the reference output here to avoid sharing types across TUs, making the output valid for bilint.

DW_TAG_imported_unit die.
