Subject: [PATCH] ir3: Don't lower to LCSSA before calling
 nir_divergence_analysis()

NIR can now calculate divergence without converting to LCSSA beforehand.
However, removing this particular instance of nir_convert_to_lcssa was
missed in commit 87cb42f9532 ("treewide: don't lower to LCSSA before calling nir_divergence_analysis()")
