I think UNLT_EXPR(a,b) means "a < b, or a and b are unordered".
If so, UNLT_EXPR(a, b) is the same as Java's "!(a >= b)",
and so letting the existing GT_EXPR handle it and then reversing
the result is correct, as (I think) Tom is saying.
In any case, the comments are in tree.def are unacceptably unclear.
