Added files:

Log message:
	* fold-const.c (swap_tree_comparison): No longer static.
	(tree_swap_operands_p): Similarly.  Return true if both operands
	are SSA_NAMEs and the first operand has a higher version number than
	the second operand.
	* tree.h (swap_tree_comparison): Prototype.
	(tree_swap_operands_p): Prototype.
	* tree-ssa-operands.c (get_expr_operands): For commutative
	operators and relational comparisons, canonicalize the
	order of the operands.
	
	* gcc.dg/tree-ssa/20040615-1.c: New test.
	* gcc.dg/tree-ssa/20030824-1.c: Update expected output to
	be less sensitive to operand ordering.
	* gcc.dg/tree-ssa/20030824-2.c: Likewise.
