If the laid-out width of the content is <= the minimum layout width, that means that the content is flexible and we can inform autolayout of this. If it's > the minimum layout width, that means that the content has reached its own "intrinsic" minimum width and we need to inform autolayout that we need more space. <rdar://problem/12960009>
