        - fixed <rdar://problem/5972943> REGRESSION(r33979): Flash clips do not play on cnn.com

        Finally blocks could clobber registers that had to remain live
        until they returned. This patch takes a conservative approach and
        makes sure that finally blocks do not reuse any registers that
        were previously allocated for the function. In the future this
        could probably be tightened up to be less profligate with the
        register allocation.
