Don't re-evaluate operands to >= and <=
Don't re-evaluate operands to >= and <=

Sometimes Rogue will combine a < or > operator with a == operator to
create >= or <=.  Unfortuantely, it was previously evaluating the
operands twice in such cases, which is very bad if they have side
effects.  We now use the new expression mode of CmdBlock so that
they are only evaluated once.
