This is the second flexbox caching change. It seeks to detect when a relayout can be avoided in the case of a stretching flex item. This heuristic can be combined, because currently we still do relayout sometimes when we do not need to. For instance currently we always relayout when a flex child is itself a column flex. This only needs to happen when the grandchildren themselves grow or shrink. That optimization is perhaps a lower priority as `flex-grow: 0 / flex-shrink: 1` is the default behavior for flex. Since this change means we more consistenly zero out the percentage part of `calc` expressions when they have circular dependencies, this causes one test to start failing (`/css/css-values/calc-min-height-block-1.html`). This is related to w3c/csswg-drafts#10969, which is pending on further discussion in the working group.
