8797 (pushlevel): Ignore argument. Do not push another binding
8798 level on the transition from the parameters to the top level
8799 of the function body; just tweak the flags and proceed.

8849 (poplevel): Delete #if 0 block. Make externals invisible
8850 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
8851 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
8852 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
8853 (duplicate-decls): For real parm decl after a forward decl,
8854 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

8858 local-over-local. Clarify comments.
8859 (pushdecl): Rewritten. There is no longer a distinction
8860 between global and local symbol values; they're all
8861 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
8862 DECL_EXTERNAL decls, and use any_external_decl to check
8863 against previous externals. Kill #if 0 blocks. Don't
8864 tolerate error_mark_node being NULL.

8866 Objective C (the only user) needs.
8867 (pushdecl_function_level): New function.
8868 (implicitly_declare): Create ordinary decls with

8884 from build_external_ref.

8889 IDENTIFIER_GLOBAL_VALUE.
