* c-common.c (shadow_warning): Delete.

	* c-common.h (free_parser_stacks, shadow_warning, sw_kind): Delete.
	* c-decl.c (warn_if_shadowing): Issue shadow warnings directly.
	* c-opts.c (c_common_parse_file): Don't call free_parser_stacks.

	arguments.
	* gcc.dg/fwritable-strings-1.c: Expect the deprecation notice.
------
	Bug 13856

	is also true.
	(merge_decls): Don't clear DECL_BUILT_IN_CLASS and
	DECL_FUNCTION_CODE when defining a built-in function.
	Don't update DECL_ESTIMATED_INSNS.

	FUNCTION_DECLs.
	* tree.h: Delete DECL_ESTIMATED_INSNS.
	* tree-inline.c (struct inline_data): Delete inlined_insns field.
	(expand_call_inline, optimize_inline_calls): Don't update
	DECL_ESTIMATED_INSNS nor inlined_insns.
	* cgraphunit.c (cgraph_analyze_function): Don't update
	DECL_ESTIMATED_INSNS.
cp:
	* optimize.c (maybe_clone_body): Don't update DECL_ESTIMATED_INSNS.
