Controling scalar and vector register allocation

Is there any way to control via OpenCL which variables will allocate scalar instead of vector registers on GCN devices? Using expressions like get_global_id(0)/64, which should contain the same value for all workitems within a wavefront, seem to be allocated on vector registers.
