8278016: Add compiler tests to tier{2,3}

[shipilev]

I have been looking at hotspot:tier4 (catch-all not in lower tiers) run logs, and realized the whole bunch of compiler tests are running there.

Since hotspot:tier4 runs a lot of vmTestbase tests, contributors seldom run it, as it takes many hours. Which means that many compiler tests are not running regularly for many contributors. But these tests are rather fast themselves and cover important compiler features.

We can properly add compiler tests to tier{2,3} to expose them on earlier tiers. The split logic between tiers is roughly: fast feature tests go into tier2, slower feature tests and debugging/printing stuff goes to tier3.

Sample times for new subgroups (think about this as "How much time they add to existing tiers"):

@shipilev again I think we need to examine this in terms of impact to our CI. We run different platforms and configurations in different tiers so the costs are not as simple as looking at one run.

Thanks,
David

Again, I can wait for those who have more insight in Oracle testing pipelines check their workflows with this change. I have no insight in Oracle infra, so somebody else have to do it. Now that Igor left, who should we be talking to?

@dholmes-ora I checked and this change does not interfere with our CI. tier2 and tier3 introduced by #5241 are not used by our CI. New tier2_compiler and tier3_compiler groups are also not used. We use different sets in CI. I am not sure how else it can affect our testing.

I also submitted our testing. I will let you know results.

[dholmes-ora]

@vnkozlov thanks for that! I didn't realize the HS testing was so isolated from the jtreg group definitions.

Thanks for your patience @shipilev .

[vnkozlov]

I don't see issues with these changes in my testing. I submitted our tier1,2,3 testing in internal infra.

Vladimir, are internal infra results good?

[vnkozlov]

Yes, all passed. You can integrate.

Thank you!
