[lworld] RFR: 8293172: [lworld] Folding of default value loads is broken

Thu Sep 1 09:55:05 UTC 2022

While working on the merge, I noticed that the constant folding of the default value load in C2 is broken and none of our tests caught it. This change fixes the incorrect `tkls->isa_inlinetype()` check than can never be true and adds a regression test.

Best regards,
Tobias
