8309974: some JVMCI tests fail when VM options include -XX:+EnableJVMCI

[dougxc]

This PR fixes a few JVMCI tests to run the ClassFileInstaller step with @run main/othervm instead of @run driver so that it inherits extra VM options passed to jtreg. This is required for these tests as they use JVMCI and module exports are needed when running ClassFileInstaller on the test class itself.

Thanks to @jonathan-gibbons for providing this solution.

I must admit I am surprised by this situation. I never imagined that @module directives would also be applied to the action to run the ClassfileInstaller as it should not need anything of that kind - it is just a simple file copying utility. But I can see how jtreg has no way to know that. Makes me wonder though whether @modules should only ever be applied to main/othervm? We not only recommend using driver mode for ClassfileInstaller we actively went through and changed a number of tests to do that!

So the fix seems fine in so far as the situation we have today, but I'm not convinced there isn't a jtreg issue here that needs further examination.

Thanks.

To be honest, it's still unclear to me why passing the extra VM options -XX:+UnlockExperimentalVMOptions -XX:+EnableJVMCI to jtreg (via the TEST_OPTS=VM_OPTIONS make control variable) causes this problem. That seems like it should be unrelated as to whether jtreg applies @module to a driver command. In any case, @jonathan-gibbons understands the jtreg issue and is taking care of it.
