fold-const.c (tree_swap_operands_p): New function to determine the prefered ordering of operands.

* fold-const.c (tree_swap_operands_p): New function to determine the prefered ordering of operands. (fold): Numerous clean-ups. Use tree_swap_operands_p when swapping operands to commutative, comparison or ternary operators. Replace uses of TREE_SET_CODE with recursive call to fold. Remove duplicate transformation of A ? B : C into !A ? C : B. From-SVN: r71438
