Summary: canUseCachedMeasurement function was not handling CSSMeasureModeAtMost correctly so a bunch of measurements that could have been reused were not. When a previous measurement used AtMost and the new one as an AtMost with a smaller constraint but still bigger than the previous computed size it should be OK to re-use the previously computed size.

Summary: Measure caching is a crucial optimization to css-layout which re-uses the output of the measure function if possible. This logic was never covered by tests.
