Pull Request resolved: https://github.com/facebook/react-native/pull/49125
Changelog: [internal]
This adds support for taking JS memory heap snapshots from Fantom tests via `Fantom.saveJSMemoryHeapSnapshot`. This can be used in one-off tests to do memory analysis and determine the existence of leaks:
```
// Warm up
Fantom.saveJSMemoryHeapSnapshot('/path/to/my/1.heapsnapshot');
// Do work
Fantom.saveJSMemoryHeapSnapshot('/path/to/my/2.heapsnapshot');
// Clean up
Fantom.saveJSMemoryHeapSnapshot('/path/to/my/3.heapsnapshot');
```
Load these snapshots in Chrome and select "Objects allocated between 1 and 2" in the dropdown to see the potentially leaked objects.
In the future we could introduce additional utilities to analyze the snapshots and do the detection automatically, e.g.:
```
// Warm up
const baseline = Fantom.takeJSMemoryHeapSnapshot();
// Do work
const before = Fantom.takeJSMemoryHeapSnapshot();
// Clean up
const after = Fantom.takeJSMemoryHeapSnapshot();
const leaks = findMemoryLeaks(baseline, before, after);
expect(leaks.sizeKB()).toBeLessThan(THRESHOLD);
```

Pull Request resolved: https://github.com/facebook/react-native/pull/49009
Changelog: [internal]
Native APIs so far have returned instance handles from React to reference nodes in the rendered UI tree, but now that we're adding support for the document API, this isn't sufficient to represent all types of nodes. Both for the document and for its `documentElement`, we don't have an instance handle from React that links to the node, but we're going to represent that differently.
This is a refactor so the existing methods use a mostly opaque `NativeNodeReference` type so we can implement it as a union of React instance handles and the future types we're going to introduce to support document.

I was adding a benchmark for rendering thousands of views and it was surprisingly fast, until I realized I wasn't wrapping the call to `root.render` in `runTask`, which means the benchmark wasn't really doing the rendering, only scheduling a microtask that was never executed.
This is a safety mechanism to prevent those mistakes.

Modifies the execution of benchmarks in CI to run benchmarks in test mode when they don't define a `verify` method.
If a benchmark uses `verify`, the test is meant to make sure that the benchmark doesn't regress in CI. If it doesn't, then running the benchmark on CI doesn't provide much value. In that case, we run a single iteration of each test case just to make sure things don't break over time.

Pull Request resolved: https://github.com/facebook/react-native/pull/48452
Changelog: [internal]
Implements a basic API to run benchmarks with Fantom (using `tinybench` under the hood):
```
import {benchmark} from 'react-native/fantom';
benchmark
.suite('Suite name', {
// options
})
.add(
'Test name',
() => {
// code to benchmark
},
{
beforeAll: () => {},
beforeEach: () => {},
afterEach: () => {},
afterAll: () => {},
},
)
.verify(results => {
// check results and throw an error if the expectations fail
});
```
Features:
* Print benchmark results in the console as a table.
* It opts into optimized builds automatically
* Verifies that optimized build is used (unless manually opting out of the check via `disableOptimizedBuildCheck`).
* Supports verification of results (making expectations and making the test fail if the benchmark doesn't meet some expectations).

Changelog: [internal]
We recently prevented tasks that run via `runTask` to synchronously call `runTask` because the execution is synchronous and we can't nest tasks in the event loop (D67107664 / https://github.com/facebook/react-native/pull/48235).
This adds `scheduleTask` to schedule tasks (also within tasks) with the right expectations (the task will not run synchronously on that call but at the right time).
It also adds `runWorkLoop` so we can run scheduled tasks if they're not scheduled from an already running task.
