9195 (pushlevel): Ignore argument. Do not push another binding
9196 level on the transition from the parameters to the top level
9197 of the function body; just tweak the flags and proceed.

9247 (poplevel): Delete #if 0 block. Make externals invisible
9248 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
9249 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
9250 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
9251 (duplicate-decls): For real parm decl after a forward decl,
9252 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

9256 local-over-local. Clarify comments.
9257 (pushdecl): Rewritten. There is no longer a distinction
9258 between global and local symbol values; they're all
9259 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
9260 DECL_EXTERNAL decls, and use any_external_decl to check
9261 against previous externals. Kill #if 0 blocks. Don't
9262 tolerate error_mark_node being NULL.

9264 Objective C (the only user) needs.
9265 (pushdecl_function_level): New function.
