final_write_globals, with write_global_declarations as default.
* toplev.c: Move invocation of wrapup_global_declarations from
compile_file to new function, write_global_declarations. Change
compile_file to use final_write_globals hook. Change
wrapup_global_declarations so writing to DECL_DEFER_OUTPUT is
conditional.
* cp/cp-lang.c: Change lang hooks so that final_write_globals does
nothing for C++.
* cp/decl.c (wrapup_globals_for_namespace): Remove special
handling of global namespace.
