[PATCH] D115981: [InstrProf] Mark counters as used in debug correlation mode

After further investigation we realized this patch is needed even for the normal block count case. Currently, it seems the optimizer does not remove globals when they are incremented because it requires a read and a write. In theory this optimization is safe so we should explicitly mark these globals as used.
