In fact `MyValue1.class` == `ldc QMyValue1;` and `MyValue1.class` and `MyValue1.class.asValueType()` are the secondary mirror.  `MyValue1.ref.class` is the primary mirror.

AFAIU, these tests fail in -Xcomp mode (pass in -Xint mode) as it's awaiting for the JIT phase 2 support (JDK-8267932) which is blocked by the core reflection support.

Would disabling -Xcomp run from these tests be a better temporay fix until JDK-8267932?
