* fold-const.c (fold_truth_not_expr): Rename from
invert_truthvalue. Give it fold_* semantics to avoid
generating garbage.
(invert_truthvalue): New function. Wrapper around
fold_truth_not_expr.
(optimize_minmax_comparison): Avoid creating garbage.
(fold_unary): Use fold_truth_not_expr for folding
TRUTH_NOT_EXPR.
(fold_ternary): Replace uses of invert_truthvalue with
fold_truth_not_expr where applicable.
* tree.h (fold_truth_not_expr): Prototype.
