Subject: inline-3.c: New test.

	* gcc.dg/inline-3.c: New test.

	* c-decl.c: (finish_function): Update call of tree_inlinable_function_p.
	* cgraph.h: (cgraph_local_info): Add can_inline_once
	(cgraph_global_info): Add inline_once.
	(cgraph_node): Add previous.
	(cgraph_remove_node): New.
	* cgraphunit.c (cgraph_mark_functions_to_inline_once): New static
	function.
	(cgraph_optimize): Call it.
	(cgraph_finalize_function):  Set inlinable flags.
	(cgraph_finalize_compilation_unit):  Actually remove the reclaimed nodes.
	(cgraph_mark_functions_to_output):  Use new inlining heuristics flags.
	(cgraph_expand_function): Likewise.
	* cgraph.c
	(cgraph_node): Put nodes into doubly linked chain.
	(cgraph_remove_node): New function.
	* flags.h (flag_inline_functions_called_once): Declare.
	* tree-inline.c: Include cgraph.h
	(inlinable_functions_p): Add extra argument to bypass limits.
	(expand_call_inline):  Obey cgraph flag.
	* tree-inline.h (tree_inlinable_function_p): Update prototype.
