8360641: TestCompilerCounts fails after 8354727

[mhaessig]

After integrating #25872 the calculation of theCICompilerCount ergonomic became dependent on the size of NonNMethodCodeHeapSize, which itself is an ergonomic based on the available memory. Thus, depending on the system, the test compiler/arguments/TestCompilerCounts.java failed, i.e. locally this failed, but not on CI servers.

This PR changes the test to reflect the changes introduced in #25872.

Testing:

• Github Actions
• tier1,tier2 plus Oracle internal testing

Thanks a lot for fixing this @mhaessig!
I left a couple of inline comments and just noticed you might want to add the copyright note as well 🙂

[dafedafe]

Is the NonNMethodCodeHeapSize value chosen "on purpose"?

[mhaessig]

Not really. We could choose it to be larger. That would just make the cutoff be at a higher CPU count. With 5 MiB, this will also perform a cutoff with less CPUs and should test both code paths on more machines.

[TheRealMDoerr]

Thank you for fixing it! I have tested it successfully. Looks good besides what other reviewers have already commented.

[mhaessig]

@vnkozlov, @dafedafe, and @TheRealMDoerr, thank you for having a look! I addressed all your comments in ab1c7d9.
