    [heap] Fix ThinString scavenge · 0503f195
    Michael Lippautz authored
    Instead of writing the forwarding pointer of this object and treating it like
    an object that would survive on scavenge just write the actual string pointer
    to the outer slot. As a consequence, the ThingString will not look like a live
    object and is handled properly when pruning the external string table.
    
    Bug: v8:8249
