    [heap] Improve accounting with ArrayBufferExtensions · 83dfd058
    Dominik Inführ authored
    Update external memory counters when using ArrayBufferExtensions. In
    case the array buffers are swept concurrently, the counters are updated
    at the beginning of the next minor/full GC. A subsequent GC is going
    to update counters faster.
    
    ArrayBufferExtension now stores the accounting_length such that
    the sweeper always knows how much memory to deduct from the external
    memory on destruction.
    
    ArrayBufferList now also tracks the size of all ArrayBuffers in it.
