Memory Panel doesn't include all objects in memory

[cj-radcliff]

If you write an app that generates a lot of string objects, and look at the memory inspector panel in DevTools, you will not see the allocated objects unless they are a widget (I think). I created 10000 String objects, and put them into a String array. In the memory panel, is see the allocated memory rise, and when I clear the collection and run GC from the memory panel, I see the memory properly reclaimed. However, in the list of objects, there is no array of strings or strings listed.

This is because by default the memory panel ignores objects from dart:core (like String).

To confirm that that is what happening, you can click on the filter button:

And then delete $sdk from the excluded class lists.

I filed #9562 to address the lack of discoverability for these filters.
