RFR(XS) [closed] : 8198924: java/lang/StackWalker/LocalsAndOperands.java timeouts with Graal

[Ekaterina Pavlova]

Hi all,

java/lang/StackWalker/LocalsAndOperands.java runs LocalsAndOperands 3 times with following set of jvm flags:
  1) -Xint -DtestUnused=true
  2) -Xcomp
  3) -Xcomp -XX:-TieredCompilation

When running with Graal as JIT (-XX:+TieredCompilation -XX:+UseJVMCICompiler -Djvmci.Compiler=graal)
3rd scenario could take more than 10 minutes and the test could fail by timeout.
Actually running LocalsAndOperands with Graal and with "-Xcomp -XX:-TieredCompilation" doesn't provide
big benefit and it would be reasonable to disable this scenario in case Graal is enabled.

Please review the change.

   testing: Tested by running the test in Graal as JIT mode.

thanks,
