Implement P0136R1, Rewording inheriting constructors.
gcc/c-family/
* c.opt (-fnew-inheriting-ctors): New.
* c-opts.c: Default to on for ABI 11+.
gcc/cp/
* call.c (enum rejection_reason_code): Add rr_inherited_ctor.
(inherited_ctor_rejection): New.
(add_function_candidate): Reject inherited ctors for copying.
(enforce_access): Use strip_inheriting_ctors.
(print_z_candidate): Likewise. Handle rr_inherited_ctor.
(convert_like_real): Avoid copying inheriting ctor parameters.
(build_over_call): Likewise. A base ctor inheriting from vbase
has no parms. Sorry about varargs.
(joust): A local constructor beats inherited with the same convs.
* class.c (add_method): Handle hiding inheriting ctors.
(one_inherited_ctor): Handle new semantics.
(add_implicitly_declared_members): Pass using_decl down.
(build_clone): A base ctor inheriting from vbase has no parms.
* cp-tree.h (DECL_INHERITED_CTOR): Store this instead of the base.
(SET_DECL_INHERITED_CTOR): Likewise.
(DECL_INHERITED_CTOR_BASE): Adjust.
* constexpr.c: Adjust.
* error.c (dump_function_decl): Decorate inheriting ctors.
* init.c (emit_mem_initializers): Suppress access control in
inheriting ctor.
* mangle.c (write_special_name_constructor): Handle new inheriting
ctor mangling.
* method.c (strip_inheriting_ctors, inherited_ctor_binfo)
(ctor_omit_inherited_parms, binfo_inherited_from): New.
(synthesized_method_walk): Use binfo_inherited_from. Suppress
access control in inheriting ctor.
(deduce_inheriting_ctor): Deleted if ambiguous ctor inheritance.
(maybe_explain_implicit_delete): Explain ambigous ctor inheritance.
(add_one_base_init, do_build_copy_constructor): Adjust.
(locate_fn_flags, explain_implicit_non_constexpr): Adjust.
(implicitly_declare_fn): Adjust.
(get_inherited_ctor): Remove.
* name-lookup.c (do_class_using_decl): Check for indirect ctor
inheritance.
* optimize.c (cdtor_comdat_group): Adjust for new mangling.
(maybe_clone_body): Handle omitted parms in base clone.
(maybe_thunk_body): Don't thunk if base clone omits parms.
* pt.c (tsubst_decl): Adjust.
(instantiate_template_1): Suppress access control in inheriting
ctor.
(fn_type_unification): Do deduction with inherited ctor.
* tree.c (special_function_p): Adjust.
gcc/
* tree-inline.c (copy_tree_body_r): Only copy the taken branch of
a COND_EXPR with constant condition.
libiberty/
* cp-demangle.c (d_ctor_dtor_name): Handle inheriting constructor.
