    [wasm][gc] Fix rare never-ending code GCs · baa9dc1d
    Clemens Backes authored
    Sometimes we were triggering a wasm code GC at a time where all native
    modules just died. Thus, no isolates took part in that GC, and it never
    finished (because no isolate would ever call {ReportLiveCodeForGC}).
    This never-ending GC would then block all other GCs for the rest of the
    life of this wasm engine.
    
    This CL fixes this by just finishing the GC immediately if no isolates
    are outstanding.
