c++: Decl module-specific semantic processing
This adds the module-specific logic to the various declaration
processing routines in decl.c and semantic.c. I also adjust the rtti
type creation, as those are all in the global module, so we need to
temporarily clear the module_kind, when they are being created.
Finally, I added init and fini module processing with the initialier
giving a fatal error if you try and turn it on (so don't do that yet).
gcc/cp/
* decl.c (duplicate_decls): Add module-specific redeclaration
logic.
(cxx_init_decl_processing): Export the global namespace, maybe
initialize modules.
(start_decl): Reject local-extern in a module, adjust linkage of
template var.
(xref_tag_1): Add module-specific redeclaration logic.
(start_enum): Likewise.
(finish_enum_value_list): Export unscoped members of an exported
enum.
(grokmethod): Implement p1779 linkage of in-class defined
functions.
* decl2.c (no_linkage_error): Imports are ok.
(c_parse_final_cleanups): Call fini_modules.
* lex.c (cxx_dup_lang_specific): Clear some module flags in the
copy.
* module.cc (module_kind): Define.
(module_may_redeclare, set_defining_module): Stubs.
(init_modules): Error on modules.
(fini_modules): Stub.
* rtti.c (push_abi_namespace): Save and reset module_kind.
(pop_abi_namespace): Restore module kind.
(build_dynamic_cast_1, tinfo_base_init): Adjust.
* semantics.c (begin_class_definition): Add module-specific logic.
(expand_or_defer_fn_1): Keep bodies of more fns when modules_p.
