    Original commit message:
      [heap] Make maximum regular code object size a runtime value.

      Executable V8 pages include 3 reserved OS pages: one for the writable
      header and two as guards. On systems with 64k OS pages, the amount of
      allocatable space left for objects can then be quite smaller than the
      page size, only 64k for each 256k page.

      This means regular code objects cannot be larger than 64k, while the
      maximum regular object size is fixed to 128k, half of the page size. As
      a result code object never reach this limit and we can end up filling
      regular pages with few large code objects.

      To fix this, we change the maximum code object size to be runtime value,
      set to half of the allocatable space per page. On systems with 64k OS
      pages, the limit will be 32k.

      Alternatively, we could increase the V8 page size to 512k on Arm64 linux
      so we wouldn't waste code space. However, systems with 4k OS pages are
      more common, and those with 64k pages tend to have more memory available
      so we should be able to live with it.

cpu-profiler: Use Handle version of SourcePositionTableIterator

The surrounding code can trigger an allocation through InliningStack
which can eventually end up allocating a line ends array.

This is fine as-is because the existing iterator code makes a copy
of the byte array. It just triggers the no_gc dcheck in debug mode.

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.

The active worker check compared the time from sending message till
response arrived from worker with the complete time the worker was
running till it responses to the spin request.

If sending back the message is slow for some reason the test fails.

Adapt the test to compare the time seen inside the worker with the
time read from main thread.

The property `process.report.reportOnFatalError`
was deemed experimental, as it was not honored
under certain scenarios (for example out of memory
conditions). The report configuration were previously
stored on the `environment` structure which was not
available on these types of fatal error cases.

The referenced PR has addressed this case (sometime
back), and the property is working as intended.

        [wasm][mac] Support w^x codespaces for Apple Silicon

        Apple's upcoming arm64 devices will prevent rwx access to memory,
        but in turn provide a new per-thread way to switch between write
        and execute permissions. This patch puts that system to use for
        the WebAssembly subsystem.
        The approach relies on CodeSpaceWriteScope objects for now. That
        isn't optimal for background threads (which could stay in "write"
        mode permanently instead of toggling), but its simplicity makes
        it a good first step.

    [mac] Set MAP_JIT only when necessary

    This is a "minimal" change to achieve the required goal: seeing that
    there is only one place where we need to indicate that memory should
    be reserved with MAP_JIT, we can add a value to the Permissions enum
    instead of adding a second, orthogonal parameter.
    That way we avoid changing public API functions, which makes this CL
    easier to undo once we have platform-independent w^x in Wasm.

Diagnostics channel (experimental module):

`diagnostics_channel` is a new experimental module that provides an API to create named channels to report arbitrary message data for diagnostics purposes.

The module was initially introduced in Node.js v15.1.0 and is backported to v14.17.0
to enable testing it at a larger scale.

With `diagnostics_channel`, Node.js core and module authors can publish contextual data about what they are doing at a given time. This could be the hostname and query string of a mysql query, for example. Just create a named channel with `dc.channel(name)` and call `channel.publish(data)` to send the data to any listeners to that channel.

```js
const dc = require('diagnostics_channel');
const channel = dc.channel('mysql.query');

MySQL.prototype.query = function query(queryString, values, callback) {
  // Broadcast query information whenever a query is made
  channel.publish({
    query: queryString,
    host: this.hostname,
  });

  this.doQuery(queryString, values, callback);
};
```

Channels are like one big global event emitter but are split into separate objects to ensure they get the best performance. If nothing is listening to the channel, the publishing overhead should be as close to zero as possible. Consuming channel data is as easy as using `channel.subscribe(listener)` to run a function whenever a message is published to that channel.

```js
const dc = require('diagnostics_channel');
const channel = dc.channel('mysql.query');

channel.subscribe(({ query, host }) => {
  console.log(`mysql query to ${host}: ${query}`);
});
```

The data captured can be used to provide context for what an app is doing at a given time. This can be used for things like augmenting tracing data, tracking network and filesystem activity, logging queries, and many other things. It's also a very useful data source for diagnostics tools to provide a clearer picture of exactly what the application is doing at a given point in the data they are presenting.

UUID support in the crypto module:

The new `crypto.randomUUID()` method now allows to generate random
[RFC 4122](https://www.rfc-editor.org/rfc/rfc4122.txt) Version 4 UUID strings:

```js
const { randomUUID } = require('crypto');

console.log(randomUUID());
// 'aa7c91a1-f8fc-4339-b9db-f93fc7233429'
```

Experimental support for `AbortController` and `AbortSignal`:

Node.js 14.17.0 adds experimental partial support for `AbortController` and `AbortSignal`.

Both constructors can be enabled globally using the `--experimental-abortcontroller` flag.

Additionally, several Node.js APIs have been updated to support `AbortSignal` for cancellation.
It is not mandatory to use the built-in constructors with them. Any spec-compliant third-party alternatives
should be compatible.

`AbortSignal` support was added to the following methods:

* `child_process.exec`
* `child_process.execFile`
* `child_process.fork`
* `child_process.spawn`
* `dgram.createSocket`
* `events.on`
* `events.once`
* `fs.readFile`
* `fs.watch`
* `fs.writeFile`
* `http.request`
* `https.request`
* `http2Session.request`
* The promisified variants of `setImmediate` and `setTimeout`

Experimental support for `AbortController` and `AbortSignal`:

Node.js 14.17.0 adds experimental partial support for `AbortController`
and `AbortSignal`.

Both constructors can be enabled globally using the
`--experimental-abortcontroller` flag.

Additionally, several Node.js APIs have been updated to support
`AbortSignal` for cancellation.
It is not mandatory to use the built-in constructors with them. Any
spec-compliant third-party alternatives should be compatible.

`AbortSignal` support was added to the following methods:

* `child_process.exec`
* `child_process.execFile`
* `child_process.fork`
* `child_process.spawn`
* `dgram.createSocket`
* `events.on`
* `events.once`
* `fs.readFile`
* `fs.watch`
* `fs.writeFile`
* `http.request`
* `https.request`
* `http2Session.request`
* The promisified variants of `setImmediate` and `setTimeout`
