Log message:
	* langhooks-def.h: Replace the simplify_function_tree hook
	with a simplify_expr hook.
	* langhooks.h: Likewise.
	* langhooks.c: Replace lhd_simplify_function_tree with
	lhd_simplify_expr.
	* c-lang.c (LANG_HOOKS_SIMPLIFY_FUNCTION_TREE): Don't define.
	(LANG_HOOKS_SIMPLIFY_EXPR): Define.
	* c-decl.c (c_expand_body): De-hook simplify_function_tree.
	* c-common.h: Declare c_simplify_expr.
	* c-simplify.c (simplify_function_tree): Rename from
	c_simplify_function_tree.  Call simplify_expr instead of
	simplify_stmt.
	(c_simplify_expr): Split out from...
	(simplify_expr): ...here.  No longer static.  Call langhook.
	(is_simple_decl_stmt): Move here from tree-simple.c.
	* tree-simple.c: Don't include c-tree.h.
	(is_simple_stmt, is_simple_compstmt): Remove.
	(is_simple_decl_stmt): Move to c-simplify.c.
	* tree.h: Declare simplify_function_tree.
	* tree-simple.h: Declare simplify_expr, add_tree.
	
	* tree-simple.c (rationalize_compound_expr): New fn.
	
	cp/:
	* cp-simplify.c (cp_simplify_expr): New fn.
	(simplify_target_expr): New fn.
	(cp_simplify_function_tree): Remove.
	* cp-lang.c (LANG_HOOKS_SIMPLIFY_FUNCTION_TREE): Don't define.
	(LANG_HOOKS_SIMPLIFY_EXPR): Define.
	* optimize.c (optimize_function): De-hook simplify_function_tree.
	* cp-tree.h: Declare cp_simplify_expr.
