This patch is OK.
There may be machine descriptions that, for whatever reason, only do
something clever with "a + b < b"; they will now lose. But, those
machine descriptions were odd anyhow; logically, they should handle both
"a + b < a" and "a + b < b" the same way.
So, your patch seems like a good improvement; as you say, it gives the
back end fewer cases to optimize.
