type reference.

* include/abg-fwd.h (remove_decl_from_scope): Declare new
function.
* include/abg-ir.h (type_base_sptr, decl_base_sptr): Move these
convenience typedef before the translation_unit declaration.
(translation_unit::{mark_type_as_used, prune_unused_types}):
Declare new methods.
(decl_base::remove_member_decl): Likewise.
(class_decl::{remove_member_decl, remove_member_type): Likewise.
* src/abg-dwarf-reader.cc (die_decl_map_type): Change this map
type so that the value is now a DIE offset, rather than a DIE.
This is because many times the lifetime of DIEs is shorter than
the one of the reader_context. Also, the die offset uniquely
designates a physical DIE even if several different instances of
logical DIE might point to it.
(struct die_hash): Remove this as it's useless now that we store
DIE offsets in the map.
(build_translation_unit): Call build_ir_node_from_die w/o setting
the called_from_public_decl flag. Prune the types that are not
used by any public decls.
(build_namespace_decl_and_add_to_ir): all build_ir_node_from_die
w/o setting the called_from_public_decl flag.
(build_ir_node_from_die): Change the only_public_decl flag into a
called_from_public_decl flag. Mark types used by public decls as
such. Adjust for the parm changes of build_qualified_type
build_pointer_type_def, build_reference_type, and
build_typedef_type.
(build_qualified_type, build_pointer_type_def)
(build_reference_type, build_typedef_type): Take a new
called_from_public_decl. Pass it to build_ir_node_from_die.
(build_var_decl): Call build_ir_node_from_die with the
called_from_public_decl flag set to true to flag the types
referenced by this variable as being used.
(build_function_decl): Take a called_from_public_decl flag as
well, as this function can now call build_function_decl itself to
build a function decl out of the value of the DW_AT_specification
attribute, for DIEs representing function definitions. Also, flag
the types referenced by public functions are being used.
* src/abg-ir.cc (translation_unit::priv::used_types_): New map for
the used types.
(translation_unit::{mark_type_as_used, prune_unused_types}):

namespace-level decls.

(canonicalize_and_add_type_to_ir): Make this static. Fix
comments.
(build_ir_node_from_die): Take a new "only_public_decl"
parameter. For DW_TAG_base_type case, use the new
canonicalize_and_insert_type_into_ir to insert the type at the
right place in the global scope making sure it is seen before the
current scope. For pointer, references and qualified types, use
canonicalize_and_insert_type_into_ir to add the type at the same
scope as its underlying type. Handle DW_TAG_{namespace,module}
using the new build_namespace_decl_and_add_to_ir function. Add
some vertical spaces and some assertions.

(canonicalize_and_add_type_to_ir): Take a naked pointer to
scope_decl rather than a smart pointer.
(build_ir_node_from_die): For DW_TAG_base_type, adjust. Support
DW_TAG_pointer_type case. For DW_TAG_{const,volatile}_type case,
make sure the qualified type is in the same scope as its
underlying type.

(parse_command_line): Adjust to consider that no option on the
command line means reading from stdin, just like --stdin. Support
the --noout option as well.
(main): Support Read the abi instr from stdin; in that case, what
was read is just serialized back to stdout, unless --noout was
supplied.
