Wasn't sure what the desired behavior was here, but I think conceptually this should fire any time one of the duration fields changes?

So it should at least fire for the initial mount.

Maybe for updates, we can check if the subtree flags includes PerformedWork?

Not sure if I'm reading too literally, but we'll still want to call onRender even if duration happened to be the same– if we did any rendering work in the subtree.

But yes, I think checking for work sounds right to me. I'll take a look at this. I think it might require a few tests updates too.

I'll pick up the test part of this now.

The change to conditionally call Profiler commit hooks only if updates were scheduled broke a few of the Profiler tests. I've fixed the tests by either:
* Adding a no-op passive effect into the subtree or
* Converting onPostCommit to onCommit

When possible, I opted to add the no-op passive effect to the tests since that that hook is called later (during passive phase) so the test is a little broader. In a few cases, this required adding awkward act() wrappers so I opted to go with onCommit instead.

// TODO: Can optimize by using a static flag to track whether a tree

Can we though? Static flags aren't specific to a render, so they wouldn't tell us if the layout effect happened to fire during the current update (which we care about for profiler)

Right but it would at least let us optimize the case where there are no layout unmount work in the tree at all. Probably not that big of a win, though, since most trees have at least one, like a DOM ref or something.

Looks good except for the static layout effects comment which I think is inaccurate.

* Don't call onCommit et al if there are no effects

Checks `subtreeFlags` before scheduling an effect on the Profiler.

* Fix failing Profiler tests

The change to conditionally call Profiler commit hooks only if updates were scheduled broke a few of the Profiler tests. I've fixed the tests by either:
* Adding a no-op passive effect into the subtree or
* Converting onPostCommit to onCommit

When possible, I opted to add the no-op passive effect to the tests since that that hook is called later (during passive phase) so the test is a little broader. In a few cases, this required adding awkward act() wrappers so I opted to go with onCommit instead.
