From: Samuel Pitoiset <samuel.pitoi...@gmail.com>
If we have a transform feedback output like:
float[2] x2_out (VARYING_SLOT_VAR1.x, 0, 0)
which is lowered by nir_lower_io_arrays_to_elements to,
float x2_out (VARYING_SLOT_VAR1.x, 0, 0)
float x2_out@5 (VARYING_SLOT_VAR2.x, 0, 0)
We have to update the destination offset to avoid overwriting
the same value.
