Log:
	* tree-ssa-ccp.c (dump_lattice_value, debug_lattice_value):
	Re-enable functions #if'd out.
	(test_default_value, likely_value, surely_varying_stmt_p,
	ccp_initialize, ccp_visit_phi_node, ccp_fold, evaluate_stmt,
	visit_assignment, visit_cond_stmt, ccp_visit_stmt):
	Convert to tuples.
	(fold_gimple_call):  Don't trip over call that simplifies to
	another call, not a constant.
	* tree-ssa-propagate.c (ssa_prop_init): Initialize in-worklist
	flag for phi nodes as well as statements.
	(valid_gimple_expression_p): Add fixme comment to remove this.
	function.  It currently has static uses, but asserts when called.
	(stmt_makes_single_load, stmt_makes_single_store):
	Convert to tuples
	(replace_phi_args_in): Convert to tuples.  Fix typo in comment.
	* gimple.c (gimple_copy_no_def_use, gimple_get_lhs,
	gimple_set_lhs): New function.
	* gimple.h (gimple_copy_no_def_use, gimple_get_lhs,
	gimple_set_lhs): Declare new function.
	* tree-cfg.c (replace_uses_by): Add comment regarding empty
	operands.
	* passes.c (init_optimization_passes): Enable pass_ccp and
	pass_store_ccp.
