* expmed.c (expand_divmod): Undo sign extensions for unsigned operands

	* cfgcleanup.c (try_forward_edges):  Don't check loop structures
	when not optimizing.
	(cleanup_cfg): Do not iterate trought delete_trivially_dead_insns
	when not expensive.
	* toplev.c (rest_of_compilation):  Duplicate loop headers only when
	optimizing;  Delete trivially dead insns early; fix optimize check.

	* Makefile.in (c-decl.o, c-objc-common.o, cgraph.o, tree-inline.o): Add
	dependency on cgraph.h
	* c-decl.c: Include cgraph.h
	(finish_function): Update call of tree_inlinable_function_p.
	* c-objc-common.c: Include cgraph.h
	* cgraph.h: New file.
	* cgraphunit.c: New file.
	* cgraph.c (cgraph_node, cgraph_edge): Move into cgraph.h
	(cgraph_nodes, cgraph_n_nodes): Globalize.
	(cgraph_finalize_function, cgraph_finalize_compilation_unit
	cgraph_create_edges, cgraph_optimize, cgraph_mark_needed_node):
	Move into cgraphunit.c
	* tree-inline.c: Include cgraph.h
	* tree-inline.c: Include cgraph.h
