WB_EnqueueInitializerForCompilation fails with "method holder must be initialized" when called for uninitialized class

      Description

      The attached JTreg test "Test.java" fails with the assertion below due to trying to compile <clinit> for the uninitialized class "LongWrapper". This seems like a special case related to the WhiteBox usage of WB_EnqueueInitializerForCompilation and should not happen otherwise.

      compiler/valhalla/inlinetypes/TestLWorldCrash.java ported to new IR framework started to crash with

      To reproduce do:
      > clone Cristian's branch:
        https://github.com/openjdk/valhalla/compare/lworld...chhagedorn:TestingFramework

      > put attached TestLWorldCrash.java under test/hotspot/jtreg/compiler/valhalla/inlinetypes

      > run as any jtreg test (uoi can use JVM from master valhalla bits as well)
