    • [REFACTOR][OBJECT] Consoldiate NodePtr/Ref/Hash/Equal to Object (#4603) · a8c36921
      * [REFACTOR][OBJECT] Consoldiate NodePtr/Ref/Hash/Equal and macros to Object.
      
      Historically, we have classes like NodePtr/Ref/HashEqual.
      After unified object protocol, these names are just alias of the object counterpart.
      Moreover, there are helper macros defined over the places for defining these object.
      
      This PR consoldiate the terminologies into the corresponding ones
      in the Object system so we have a clean and consistent API moving forward.

    • [REFACTOR][RUNTIME] Update NDArray use the Unified Object System (#4581) · 55bd786f
      * [REFACTOR][RUNTIME] Move NDArray to Object System.
      
      Previously NDArray has its own object reference counting mechanism.
      This PR migrates NDArray to the unified object protocol.
      
      The calling convention of NDArray remained intact.
      That means NDArray still has its own type_code and
      its handle is still DLTensor compatible.
      
      In order to do so, this PR added a few minimum runtime type
      detection in TVMArgValue and RetValue only when the corresponding
      type is a base type(ObjectRef) that could also refer to NDArray.
      
      This means that even if we return a base reference object ObjectRef
      which refers to the NDArray. The type_code will still be translated
      correctly as kNDArrayContainer.
      If we assign a non-base type(say Expr) that we know is not compatible
      with NDArray during compile time, no runtime type detection will be performed.
      
      This PR also adopts the object protocol for NDArray sub-classing and
      removed the legacy NDArray subclass protocol.
      Examples in apps/extension are now updated to reflect that.
      
      Making NDArray as an Object brings all the benefits of the object system.
      For example, we can now use the Array container to store NDArrays.
