Summary: If there is a single child which is flex grow and flex shrink then instead of measuring and then shrinking we can just set the flex basis to zero as we know the final result will be that the child take up all remaining space.

1baa239389 Remove isTextNode optimization
Summary: Scrolling through feed and logging when this optimization is hit leads to... 0 logs. If anything this just adds to confusion. It was initially added due to instinct and not data, which was a mistake. I am happy to add some similar optimization in the future if we have data that it is useful in real world situations, currently it just leads to bugs and confusion though.

46823878a5 BREAKING - Make first parameter of measure and print functions CSSNodeRef instead of just context
Summary: To perform some JNI optimizations for java we need a reference to the node in the measure function. This updates the API to provide the whole node as input instead of just the context.

4d0e657653 Fix bug in canUseCachedMeasurement causing unneeded double measure
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.

1f300a58fb Free memory used in tests to enable use of valgrind
Summary: Its very usefull to be able to run valgrind on the tests and benchmarks. We were previously not freeing test memory so valgrind output was very messy.

1051c39a59 Add tests for measure caching
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.
