The closure-conversion transformation is not enabled yet. This commit only adds the support for it to FlowGraphBuilder and StreamingFlowGraphBuilder. More work should be done before enabling the transformation; most mportantly, the 'platform.dill' file that is used in the Kernel isolate and is loaded by VM for linking with executed programs should be separated. The former should receive a file not touched by the transformation, and the latter should receive a transformed one.
