[lworld] RFR: 8280270: [lworld] JITs miss some klass initialization checks for defaultvalue

[Tobias Hartmann]

C1 and C2 miss some klass initialization checks for defaultvalue.

Long term, we should add support for patching defaultvalue in C1 (tracked by [JDK-8265067](https://bugs.openjdk.java.net/browse/JDK-8265067)).

Thanks,
Tobias
