Revert "Optimize typeof(T1).IsAssignableFrom(typeof(T2))"

Reverts #1195

@jkotas, @AndyAyersMS - in the latest runtime-coreclr outerloop runs I see a systematic failure in two JIT tests (_il_reli_conv, _il_relu_conv) crashing on a JIT assert:

Assertion failed '(tree->gtFlags & (GTF_SIDE_EFFECT & ~GTF_CALL)) == 0' in 'Test:Main():int' (IL size 561)

At today infra standup @safern speculated that this rollback commit should fix the issue but I'm not sure and I see the problem reproing in the latest outerloop runs - can you please clarify so that I know whether I should file a new issue tracking this?

An example of such failed run is here:

Thanks

Tomas

I see that for that assertion in particular hitting the outerloop job is this issue: #31665

[AndyAyersMS]

That assert is from a different change, #1751, that wasn't rolled back. There is already an issue, #31665.

OK, great, thanks for clarification! Is there an ETA for a fix - in essence, do we need to temporarily disable the tests to avoid showing Steve and Chris a zero per cent outerloop pass rate again?

For dotnet/runtime, outerloop is designed to catch what falls through the cracks and there is always going to be something falling through the cracks given the scope of the repo.

We should fix the metrics that we are tracking where we are trying to hit 100%. I think we should be tracking pass rates of the inner loop tests.

Hmm, the problem is that today innerloop tests = PR tests that are quite noisy as people are (naturally) sometimes testing buggy changes. We would need to create a new flavor of "innerloop rolling build" that doesn't exist today AFAIK.

That; or we can be tracing number of failing tests on merged PRs, or number of retries people end up doing to get a green CI before merging the PR.

I'm not sure if the coreclr-outerloop job is tracked by CI council, I think for dotnet/runtime we only track runtime CI build definition. @ViktorHofer@Chrisboh ?

[ViktorHofer]

You can find the build definitions that we track here in the dashboard: https://dnceng.visualstudio.com/public/_dashboards/dashboard/40ac4990-3498-4b3a-85dd-2ffde961d672

Hmm, I just tried that in three different browsers and it claims that "I'm not a member of this team project". When I logged into Azure DevOps it shows me a bunch of "organizations" but I don't see "dnceng.visualstudio.com" among them. Have you got any idea how the access rights to the dashboard are managed? Even weirder, I was looking at the dashboards during our CI council meetings and I'm sure that it worked then.

When I click on the link that Viktor provided, for some reason it says I'm not signed in. So, I then have to sign in and then navigate to the dashboard. Perhaps that's what you're seeing?

[trylek]

Thanks @chcosta for your quick response; the initial part works the same for me - the infra prompts me to log in - but then it just shows me a list of "organizations" - presumably the ones I'm authorized to access - and dnceng.visualstudio.com is not among them, nor can I circumvent this by pasting the link to the dashboard URL in the login web page, at least I haven't found a way yet.

[chcosta]

that doesn't make sense, I see you as a "User" on dnceng. In the list of organizations, I see dnceng as dev.azure.com/dnceng rather than dnceng.visualstudio.com.

[trylek]

Ahh, great, thanks @chcosta, after massaging Viktor's link as follows it works for me just great:
