Make sure {type,obj}ArrayOopDesc accessors check the bounds

      Description

        I was debugging some new VM patch, and figured it was a memory stomp due to wrong index passed to objArrayOopDesc::obj_at_put. That method does not assert the index at all, which hides the errors and silently corrupts the heap, until something else discovers it. Some objArrayOopDesc accessors do verify the index against the bounds.

        Same thing goes for typeArrayOopDesc.
