freedreno/ir3: insert mov if same instruction in the outputs.
For example,
result0 = texture(sampler[indexBase + 5], coords);
result1 = texture(sampler[indexBase + 0], coords);
result2 = texture(sampler[indexBase + 0], coords);
out_result0 = result0;
out_result1 = result1;
out_result2 = result2;
In this kind of case we need to insert an extra mov to the outputs
so that the result could be assigned to each register respectively.
