501 (objc_mark_locals_volatile): Update for new bindings structures.
502 (global_bindings_p): Honor c_override_global_bindings_to_false.
503 (pushlevel): Rename to push_scope; take no arguments; use the

505 (poplevel): Rename to pop_scope; totally rewritten for new bindings
507 (diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
508 C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
