11u downport: Mark as jdk11u-jvmci-defer. The patch applies clean, but the test hangs. Given the many missing JVMCI changes I skip this one.

I didn't notice that rule before. Thanks Tobias for your reminder. Will do next time.

ILW = Assert due to invalid compilation level, with -XX:+BootstrapJVMCI and -XX:TieredStopAtLevel=1, disable JVMCI or remove flags = HLL = P4
