JDK-8150292 - CompilerWhiteBoxTest.MODE should contain only the execution mode
Description
As of https://bugs.openjdk.java.net/browse/CODETOOLS-7901583 is resolved it's possible now to set vm.compMode in the correct value and rely on this at @requires expressions.

What should be done here:
1) A new setter for the vm.compMode property to be developed.
2) Tests using their own logic to see if the applicable compMode is used to be modified.
Comments
jvmci/compilerToVM/IsMatureTest.java has different checks depending on java.vm.info.

FC Extension Request Justification: reduce false negative test results, speed-up test execution Risk: low, declarative changes and corresponding clean up in tests Remaining work: update the tests which use java.vm.info directly - hotspot/compiler/codecache/stress/OverloadCompileQueueTest.java and the tests which use this property indirectly thru - hotspot/compiler/intrinsics/mathexact/sanity/IntrinsicBase.java - hotspot/compiler/whitebox/CompilerWhiteBoxTest.java Due date: in 2w ~ 1st Jul
