Fix D3D Shader Debugger source variable mapping for matrix

Browse Source 
If the matrix was mapped to a single register (i.e. special SSA ID -1) then it was expanded because a single element was mapped to different register the expansion was not happening because the matrix row was being set to be emitted in the code which tries to recombine rows

Apply similar fix for vector recombining code, do not emit the whole vector by default when assigning a single element and let the recombining code mark if the whole vector should be emitted
