9802 local-over-local. Clarify comments.
9803 (pushdecl): Rewritten. There is no longer a distinction
9804 between global and local symbol values; they're all
9805 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
9806 DECL_EXTERNAL decls, and use any_external_decl to check
9807 against previous externals. Kill #if 0 blocks. Don't
9808 tolerate error_mark_node being NULL.

9810 Objective C (the only user) needs.
