Under Windows 'ipc' communication requires the other process to format its messages with 'IPC framing protocol'. Otherwise, an assert is triggered in libuv. This commit changes child-process-read benchmark to use stdout to communicate with parent process. It also adds child-process-read-ipc.js to benchmark IPC communication using child node process.
