[lworld] RFR: 8372917: [lworld] C2 compilation bailout asserts due to label in inconsistent state

[Tobias Hartmann]

When an expected compilation bailout (like 'CodeCache is full') happens during matching, not all nodes might be visited and therefore the Valhalla specific `verified_entry` label might be in inconsistent state (used but not bound). We should simply reset it when we bail out. For more details, see JBS.

Thanks,
Tobias
