Retrieve a particular spacebase register associated with the virtual address space
basespace.  This register serves as a base offset to anchor basespace within
its containing space.
@param basespace is the virtual space to find a spacebase register for
@param i is the index of the particular spacebase register
@return a reference to the spacebase register
