fold-const.c (swap_tree_comparison): No longer static.

        * 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.
