This commit improves setImmediate() performance by moving the try-finally block that wraps callback execution into a separate function because currently v8 never tries to optimize functions that contain try-finally blocks. With this change, there is a ~20-40% improvement in the included setImmediate() depth benchmarks. The breadth benchmarks show a slight improvement.
