Port r16098 (328ff5f7) Original commit message: This change implements a simple data-flow analysis pass over captured objects to the existing escape analysis. It tracks the state of values in the Hydrogen graph through CapturedObject marker instructions that are used to construct an appropriate translation for the deoptimizer to be able to materialize these objects again. This can be considered a combination of scalar replacement of loads and stores on captured objects and sinking of unused allocations.
