v8.stopCoverage()

v8.stopCoverage() 方法允许用户停止由 NODE_V8_COVERAGE 启动的覆盖率收集，这样 V8 就可以释放执行计数记录并优化代码。如果用户希望按需收集覆盖率，可以与 v8.takeCoverage() 一起使用。

【The v8.stopCoverage() method allows the user to stop the coverage collection started by NODE_V8_COVERAGE, so that V8 can release the execution count records and optimize code. This can be used in conjunction with v8.takeCoverage() if the user wants to collect the coverage on demand.】
