Use correct arrayBaseNode in BoolArrayStoreTransformer for OffHeap

[rmnattas]

When BoolArrayStoreTransformer insert runtime checks for unknown array type stores generated by bastore bytecode, it uses the target array address (without offset) as the base array to load the vft-symbol and check the class type. With OffHeap that node would be the dataAddrPtr instead of array base.

This PR checks if its the dataAddrPtr and uses the correct array base node for the generated check.
