* cgraphunit.c (cgraph_lower_function): Revert last change.
	* targhooks.c (default_static_chain): Use !DECL_STATIC_CHAIN
	instead of DECL_NO_STATIC_CHAIN.
	* tree-cfg.c (verify_gimple_call): Likewise.
	* tree-nested.c (get_chain_decl, get_chain_field,
	convert_tramp_reference_op, convert_gimple_call): Likewise.
	(convert_all_function_calls): Likewise.  Always set or clear
	DECL_STATIC_CHAIN initially, for !n->outer clear it.
	(lower_nested_functions): Remove DECL_NO_STATIC_CHAIN checking code.
	* c-parser.c (c_parser_declaration_or_fndef): Set DECL_STATIC_CHAIN
	if nested.
	* print-tree.c (print_node): Handle DECL_STATIC_CHAIN instead of
	DECL_NO_STATIC_CHAIN.
	* config/i386/i386.c (ix86_static_chain): Use !DECL_STATIC_CHAIN
	instead of DECL_NO_STATIC_CHAIN.
	(ix86_function_regparm, find_drap_reg): Likewise.  Don't test
	decl_function_context.
	* varasm.c (initializer_constant_valid_p): Likewise.
	* tree.h (DECL_NO_STATIC_CHAIN): Renamed to ...
	(DECL_STATIC_CHAIN): ... this.
	* config/moxie/moxie.c (moxie_static_chain): Use !DECL_STATIC_CHAIN
	instead of DECL_NO_STATIC_CHAIN.

	* method.c (make_thunk, make_alias_for): Don't set
	DECL_NO_STATIC_CHAIN.
	* decl.c (builtin_function_1, grokfndecl): Likewise.
	* lex.c (build_lang_decl): Likewise.

	* gcc-interface/utils.c (gnat_pushdecl): Don't set
	DECL_NO_STATIC_CHAIN, set DECL_STATIC_CHAIN for
	nested functions.

	* testsuite/gcc.target/i386/pr12329.c: Adjust.
