Even though these tests are marked with:

 * @requires !vm.graal.enabled & vm.opt.final.UseVtableBasedCHA == true

they are run in tier5 and fail with:

Should be reproducible with the following in a galahad-ee workspace:

make LOG=info CONF=linux-x64-debug TEST="compiler/cha compiler/intrinsics/klass/CastNullCheckDroppingsTest.java compiler/c2/cr7200264/TestSSE4IntVect.java compiler/c2/cr7200264/TestSSE2IntVect.java" JTREG_JAVA_OPTIONS="-XX:+UnlockDiagnosticVMOptions -XX:TieredStopAtLevel=3 -XX:+StressLoopInvariantCodeMotion -XX:+StressRangeCheckElimination -XX:+StressLinearScan -XX:+UnlockExperimentalVMOptions -XX:+UseJVMCICompiler" test

The problem is that vm.graal.enabled is false because -XX:TieredStopAtLevel=3 is set but then @run disables TieredCompilation which leads to TieredStopAtLevel=3 having no effect and essentially re-enabling Graal. I think '& (vm.opt.TieredStopAtLevel == null | vm.opt.TieredStopAtLevel==4)' should be added to these tests. We already have that in test/hotspot/jtreg/runtime/exceptionMsgs/IncompatibleClassChangeError/IncompatibleClassChangeErrorTest.java

ILW = Tests fail (test bugs), several tests with Graal on tier5, no workaround = MMH = P3
