    Do not try to logical fold floating point relations.

    relation_fold_and_or looks for relations among common operands feeding
    logical ands and ors.  With no knowledge of NANs, it should not attempt
    to do this with floating point ssa names.

            * gimple-range-fold.cc (old_using_range::relation_fold_and_or):
            Do not attempt to fold HONOR_NAN types.
