RFR(S): 8151707: Mark hotspot tests which ignore external VM flags

[Christian Tornqvist]

Hi Dima,

I don't think this is the right way to go, we need to stop with the flag rotation madness and this is another step in trying to preserve that. Tests need to explicitly define how they're supposed to run, this is not getting us any nearer that. I don't think we should make this change.

Thanks,
Christian

Subject: RFR(S): 8151707: Mark hotspot tests which ignore external VM flags

Hello,

Could you review a simple fix with introduces a new jtreg keyword: 
"noflags".
The purpose of this keyword is to mark those tests which ignore VM flags given outside (on the command line).
It will allow to not run such tests many times in different VM configurations as we do every night, but run only once.

Note: this fix will not affect execution, so the tests labeled as "noflags" will not be automatically filtered out in case of external VM flags are given. It will just allow to not execute such tests:
   # jtreg  -k:'!noflags' -vmflags:'-XX:+UseG1GC -Xint' test/

Note2: All the tests modified tests are manually reviewed to be sure that they indeed ignore external VM flags.
