>> [JDK-8346781](https://bugs.openjdk.org/browse/JDK-8346781) changed `JVMCIServiceLocator` such that set of providers is computed eagerly in `JVMCIServiceLocator.<clinit>`. There are some JVMCI test classes that directly subclassed `JVMCIServiceLocator` which meant deadlock could occur between the main thread running the test and a JVMCI compiler thread. This PR fixes this by ensuring that `JVMCIServiceLocator` providers are separate classes from the main test class.

Not sure I understand the question: `UseJVMCINativeLibrary` is a JVMCI flag just like all other JVMCI flags.
