This allows the repl to function normally while using the
`--no-harmony-sharedarraybuffer` V8 flag.
It also fixes using workers while using the
`--no-harmony-atomics` V8 flag.

Allow calling eventLoopUtilization() directly on a worker thread:
const worker = new Worker('./foo.js');
const elu = worker.performance.eventLoopUtilization();
setTimeout(() => {
worker.performance.eventLoopUtilization(elu);
}, 10);
Add a new performance object on the Worker instance that will hopefully
one day hold all the other performance metrics, such as nodeTiming.
Include benchmarks and tests.

This removes 'to Number' casting in multiple benchmarks (which is
handled by the benchmark runner) and cleans up some var usage in changed
benchmarks.

Add a raw `MessagePort` benchmark that does not ping back and forth
between different threads, unlike the `echo.js` benchmark, as there
are some performance differences between single-threaded and multi-
threaded operation, and a single-threaded Environment can be somewhat
easier to work with when profiling.

Having an experimental feature behind a flag makes change
if we are expecting significant breaking changes to its API.
Since the Worker API has been essentially stable since
its initial introduction, and no noticeable doubt about
possibly not keeping the feature around has been voiced,
removing the flag and thereby reducing the barrier to experimentation,
and consequently receiving feedback on the implementation,
seems like a good idea.
