When laying out a block-level box that avoids floats, if we know that
its size doesn't depend on the available space, we can take a fast path
and only lay it out once. If its size depends on the available space,
we may have to lay it out multiple times, which can be slower.
This patch improves the check for this dependency on the available space.
For example, `min-width: 200px; width: 100px; max-width: stretch` was
previously considered to depend on the available space because of
`max-width`. However, `max-width` is irrelevant when the min size is
greater than the preferred size.
