[PATCH] D19827: Do not disable completely loop unroll according to optimization level.

I think the blog comment is right. The pragma should make the loop unroll even in /Os. I think it is essential to allow the user to optimize some specific loops even if he generally wants to optimize for size the rest of the code. I will add tests that show the behavior of the loop unroll pass when optnone or optsize are specified.
