bench: Remove _bench_timer (no loner used)

benchmark/_bench_timer.js

-/*
- * This is a simple addition to allow for higher resolution timers.
- * It can be used to track time for both synchronous or asynchronous
- * calls. For synchronous calls pass a callback function like so:
- *
- *  var timer = require('./_bench_timer');
- *
- *  timer('myTest', function() {
- *    for (var i = 0; i < 1e6; i++)
- *      // ... run something here
- *    }
- *  });
- *
- * For asynchronous timers just pass the name. Then run it again with
- * the same name to finish it:
- *
- *  timer('checkAsync');
- *  setTimeout(function() {
- *    timer('checkAsync');
- *  }, 300);
- *
- * When this happens all currently queued benchmarks will be paused
- * until the asynchronous benchmark has completed.
- *
- * If the benchmark has been run with --expose_gc then the garbage
- * collector will be run between each test.
- *
- * The setTimeout delay can also be changed by passing a value to
- * timer.delay.
