Do not change environment between simulate and scope with no observable side-effects in HandlePropertyAssignment.
LChunkBuilder reconstructs the environment by applying simulates. A scope with no observable side-effects has no simulates. If the scope deoptimizes, then LChunkBuilder would miss the changes to the environment between the last simulate and the scope.
