remove operand swap when processing EQ LT LE

[viruscamp]

test case

function lt_const(a,b,c)
    b = a>3
    b = 3<a
    b = not (a<=3)
    b = not (3>=a)
end

function lt_if(a,b,c)
    if a>3 then
        b()
    end
    if not (a<=3) then
        c()
    end
end

function eq_const(a,b,c)
    b = a==3
    b = 3==a
end

bug, calucate order changed

function lt_function(a,b,c)
    a = b()>c()
    a = c()<b()
    a = not (b()<=c())
    a = not (c()>=b())
end
