On-heap TypedArrays have empty ArrayBuffers that are not supposed to be accessed directly. Such ArrayBuffers materialize properly when accessed via their TypedArrays. The queryObjects() sidesteps the bottleneck and finds empty ArrayBuffers by iterating the heap. When preview TypedArrays are constructed for the found ArrayBuffers, they get nullptr data pointers. This CL converts all on-heap TypedArrays into off-heap TypedArrays in queryObjects to make sure that all found ArrayBuffers are valid.
