Summary: This declares a few globals that were missing in our `global.js` Flow declaration file: * `process` * `performance` with its current definition. We'll replace it with the new API when we replace `setupPerformance` with `setupWebPerformance`. * `navigator` * `setImmediate` * `clearImmediate` Eventually we should stop including all DOM definitions that Flow provides out of the box and define only what we provide (which is pretty much this file).
