10313 (pushdecl): Rewritten. There is no longer a distinction
10314 between global and local symbol values; they're all
10315 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
10316 DECL_EXTERNAL decls, and use any_external_decl to check
10317 against previous externals. Kill #if 0 blocks. Don't
10318 tolerate error_mark_node being NULL.
