* doc/gty.texi ("Inheritance and GTY"): Make it clear that
to use autogenerated markers for a class-hierarchy, every class
must have a GTY marker.
* gengtype.h (struct type): Add linked list of subclasses to
the "s" member of the union.
(add_subclass): New decl.
* gengtype-state.c (read_state_struct_type): Set up subclass
linked list.
* gengtype.c (get_ultimate_base_class): New.
(add_subclass): New.
(new_structure): Set up subclass linked list.
(set_gc_used_type): Propagate usage information to subclasses.
(output_mangled_typename): Use get_ultimate_base_class.
(walk_subclasses): Use the subclass linked list, avoiding an
O(N^2) when writing out all types.
(walk_type): Issue an error if the base class is missing a tag,
rather than generating bogus C code. Add a gcc_unreachable
default case, in case people omit tags from concrete subclasses,
or get the values wrong.
(write_func_for_structure): Issue an error for subclasses for
which the base doesn't have a "desc", since otherwise the
autogenerated routines for the base would silently fail to visit
any subclass fields.
(write_root): Use get_ultimate_base_class, tweaking constness of
tp to match that function's signature.

* gengtype-parse.c (opts_have): Drop "static" so that
we can use this from gengtype.c.
* gengtype.c (set_gc_used_type): Mark any base class as used;
update field traversal to visit inherited fields.
(output_mangled_typename): Convert references to classes within
an inheritance hierarchy to reference the ultimate base class,
since only it will have gt_ functions.
(get_string_option): New.
(walk_subclasses): New.
(walk_type): Treat GTY structs that have a "desc" as being the
root of an inheritance hierarchy. Generate a switch on it
within the marking function which walks all subclasses, adding
cases for them via walk_subclasses. For subclasses, visit all
fields of the type (including inherited ones).
(write_func_for_structure): Don't write fns for subclasses, only
for the ultimate base class within an inheritance hierarchy.
Subclasses-marking will be handled by the base class marking
functions.
(write_types): Likewise.
(write_local_func_for_structure): Likewise.
(USED_BY_TYPED_GC_P): Emit allocators for subclasses that have
a "tag" option (and are thus concrete subclasses).
(write_root): Use the marker function for the ultimate base class.
* gengtype.h (FOR_ALL_INHERITED_FIELDS): New.
(opts_have): Add declaration.
