Subject: cgraph.c (cgraph_insert_node_to_hashtable): New function.

	* cgraph.c (cgraph_insert_node_to_hashtable): New function.
	* cgraph.h (cgraph_node): Add inline_decl.
	(cgraph_insert_node_to_hashtable): Declare.
	(save_inline_function_body): Declare.
	* cgraphunit.c (verify_cgraph_node): Inline edges might point to inline
	clones.
	(cgraph_preserve_function_body_p): Do not presrve when dump is enabled.
	(cgraph_function_versioning): Update call of tree_function_versioning.
	(save_inline_function_body): New function.
	* function.h (struct function): Kill saved_eh, saved_cfg, saved_args,
	saved_static_chain_decl, saved_blocks and saved-unexpanded_var_list.
	* ipa-inline.c (cgraph_mark_inline_edge): Look for inline clones.
	(cgraph_default_inline_p): Likewise.
	(cgraph_decide_inlining_incrementally): Likewise.
	* tree-inline.c (inline_data): Kill saving_p add update_clones_p.
	(copy_bb): Kill saving; do updating of clones.
	(copy_cfg_body): Kill saving.
	(initialize_inlined-parameters): Likewise.
	(expand_call_inline): Likewise.
	(save_body): Kill.
	(tree_function_versioning): New parameter "update_clones".
	(inlining_p): Kill saving.
	* tree-inline.h (tree_function_versioning): Update prototype.
	* tree-optimize.c (tree_rest_of_compilation): Use clonning instead of
	saving.
