When Arrays of Arrays was enabled, the following piglit test regressed on snb,
bdw, bsw, byt, hsw, ivb, and skl:

piglit.spec.arb_program_interface_query.arb_program_interface_query-getprogramresourceindex


/tmp/build_root/m64/lib/piglit/bin/arb_program_interface_query-getprogramresourceindex

piglit: debug: Requested an OpenGL 3.2 Core Context, and received a matching
3.3 context

Invalid index for 'vs_input2': expected INVALID_INDEX but got 0

    docs: Mark AoA as done for i965

However, it may be one of the two previous patches that triggers the
regression.

In addition, the following piglit tests were enabled with AoA, but fail:

piglit.spec.glsl-1_10.execution.varying-packing.simple uvec3 arrays_of_arrays
piglit.spec.glsl-1_10.execution.varying-packing.simple ivec3 arrays_of_arrays

Standard Output:
Probe color at (0,0)
  Expected: 0.000000 1.000000 0.000000 1.000000
  Observed: 1.000000 1.000000 1.000000 1.000000

Standard Error

Failed to link: error: fragment shader uses too many input components (132 >
