intel/nir: Use nir_shrink_vec_array_vars
Shader-db results on Kaby Lake:
total instructions in shared programs: 15177605 -> 15176765 (<.01%)
instructions in affected programs: 4259 -> 3419 (-19.72%)
helped: 1
HURT: 0
total spills in shared programs: 10954 -> 10855 (-0.90%)
spills in affected programs: 295 -> 196 (-33.56%)
helped: 1
HURT: 0
total fills in shared programs: 22222 -> 22117 (-0.47%)
fills in affected programs: 417 -> 312 (-25.18%)
helped: 1
HURT: 0
The helped shader is from the OglCSDof synmark test. On my Kaby Lake
laptop, the actual framerate of the benchmark didn't appear to improve
beyond the noise.
