[Mesa-dev] [PATCH 41/78] i965/nir/vec4: Implement non-equality ops on vectors

[Eduardo Lima Mitev]

From: Antia Puentes <apuentes at igalia.com>

Adds NIR ALU operations:
   * nir_op_bany_fnequal2
   * nir_op_bany_inequal2
   * nir_op_bany_fnequal3
   * nir_op_bany_inequal3
   * nir_op_bany_fnequal4
   * nir_op_bany_inequal4
