    [compiler] Clear reconstructible ObjectData after serialization · 0362bc6c
    Jakob Gruber authored
    This is another step towards improving TSAN and test coverage of
    concurrent paths.
    
    By purging reconstructible (background-serialized or never-serialized)
    ObjectData instances from the cache after serialization, we increase
    ObjectData-construction activity on the background thread.
    
    Note that this means ObjectData is no longer canonicalized - two
    instances can point at the same underlying object. Losing this
    property is unfortunate, but we can revert back to it once work on the
    concurrency project is further advanced.
